An integrated structure for self-driving and traction of energy storage power vehicles

Abstract

An integrated self-driving and traction structure for energy storage power vehicles is disclosed. When the power vehicle needs to be towed, the tow ring at the end of the tow bar is attached to the tractor vehicle, which then tows the power vehicle. When the power vehicle needs to drive itself, it is driven by a power vehicle drive unit. Since the steering seat is rotatably mounted at the front of the power vehicle, the steering seat is rotated by the tow bar using a control handle, thus steering the entire power vehicle. The control handle can also be used to drive the power vehicle forward or backward. After the power vehicle moves into position, a braking device applies braking force to the steering wheels, fixing the power vehicle in place. This structure allows the power vehicle to be both towed and self-driving, solving the problems of time-consuming, labor-intensive, and inefficient operation of traditional energy storage power vehicles.

Description

Technical Field

[0001] This invention relates to the field of aircraft ground energy storage power vehicle technology, and specifically to an integrated structure for self-driving and traction of an energy storage power vehicle. Background Technology

[0002] When the aircraft ground-based energy storage vehicle supplies power to the aircraft, it is towed to the vicinity of the aircraft by a tractor. Generally, once close to the aircraft, the tractor cannot move further and the vehicle needs to be manually pushed to the aircraft's power interface. Due to its weight, the vehicle is difficult for two or three people to push. After supplying power to one aircraft, the vehicle must also be manually pushed to the corresponding aircraft position to supply power to a nearby aircraft, which is very strenuous. After supplying power, the vehicle needs to be towed to a charging station for charging, requiring manual adjustment of its position before it can be attached to the tractor. Given these technical drawbacks, this non-self-propelled energy storage vehicle is time-consuming, labor-intensive, and has very low work efficiency. Summary of the Invention

[0003] In order to overcome the shortcomings of the above technologies, the present invention provides an integrated structure for self-driving and traction of energy storage power vehicles that is easy to operate and reliable to use.

[0004] The technical solution adopted by this invention to overcome its technical problems is:

[0005] A self-propelled and traction integrated structure for an energy storage power vehicle includes a power vehicle, wherein a power source and an energy storage battery pack connected to the power source are installed in the power vehicle, and further includes:

[0006] Power vehicle drive unit, used to drive the power vehicle to move;

[0007] A steering seat has steering wheels rotatably mounted on its left and right ends respectively. A flange is rotatably mounted on the upper end of the steering seat through bearing I. The flange is fixed to the front side of the lower end of the power vehicle.

[0008] The braking device, located in the steering seat, is used to generate braking force on the steering wheels;

[0009] The drawbar is rotatably mounted on the front end of the steering seat via pivot II;

[0010] The control handle is located at the head end of the pull rod; and

[0011] The traction ring is installed at the head end of the traction rod.

[0012] Furthermore, the aforementioned power vehicle drive device includes a rear axle and a motor installed at the lower rear side of the power vehicle. Drive wheels are respectively installed at the left and right ends of the rear axle. The output shaft end of the motor is connected to the input end of the rear axle. A motor controller is installed on the power vehicle, and the motor is connected to the energy storage battery pack via the motor controller.

[0013] Furthermore, the aforementioned braking device includes a guide groove disposed in the steering seat along the front-rear direction, a brake rod slidably installed in the guide groove and horizontally disposed in the left-right direction, a guide rod I horizontally slidably inserted into the steering seat along the front-rear direction, and a push rod installed at the front end of the guide rod I. The length of the brake rod is greater than the wheel track between the two steering wheels. The rear end of the guide rod I is connected to the brake rod, the front end of the spring I is in contact with the brake rod, and its rear end is connected to the steering seat. When the traction rod rotates to the vertical state, its rear end drives the push rod to move rearward until the left and right ends of the brake rod respectively contact the wheel surfaces of the corresponding steering wheels on the same side and compress the spring I.

[0014] For ease of operation, a swing bracket is also included. The middle part of the swing bracket is rotatably mounted on the traction rod via a pivot I. A foot pedal is installed at the front end of the swing bracket, and a hook is installed at its rear end. A protrusion is installed on the steering seat, and a groove is formed between the rear end of the protrusion and the steering seat. The rear end face of the hook is a guide slope I, and the front end face of the protrusion is a guide slope II. When the traction rod rotates to the rear end, the guide slope I of the hook contacts the guide slope II of the protrusion, and the hook swings upward. When the traction rod rotates to a vertical position, the hook is located in the groove.

[0015] To improve ease of use, a tension spring is also included. One end of the tension spring is connected to the steering seat, and the other end is connected to the traction rod. When the tension spring is in a free state, the traction rod is in a vertical state.

[0016] To enable the operation handle, a rotating box is also included, which is rotatably mounted on the head end of the traction rod via bearing II. The operation handle is mounted on the rotating box, and when the operation handle is rotated to the front end or the rear end, it is locked and fixed relative to the traction rod by a locking device.

[0017] Furthermore, the aforementioned locking device includes two locking pins that are vertically slidably installed in the rotating box. Spring III is fitted onto the locking pins, with its upper end connected to the rotating box and its lower end connected to the locking pins. The front end of the traction rod is provided with two locking holes II, and the rear end of the traction rod is provided with two locking holes I. When the operating handle is rotated to the front end, the two locking pins are inserted into the corresponding locking holes I under the elastic force of spring III. When the operating handle is rotated to the rear end, the two locking pins are inserted into the corresponding locking holes II under the elastic force of spring III. The upper ends of the two locking pins are connected by a handle.

[0018] To achieve buffering, a guide rod II is slidably inserted into the head end of the aforementioned traction rod in the horizontal direction. A traction ring is installed at the head end of the guide rod II. A boss is installed at the tail end of the guide rod II. A partition is installed inside the traction rod. The front end of the partition forms a front cavity, and the rear end of the partition forms a rear cavity. Spring II is located in the front cavity and is fitted onto the guide rod II. The front end of spring II is connected to the guide rod II, and its rear end contacts the partition. Several disc springs are located in the rear cavity and are fitted onto the guide rod II. The front end of the disc springs contacts the partition, and its rear end contacts the boss.

[0019] Furthermore, it also includes a rotary switch, which is electrically connected to the motor controller.

[0020] The beneficial effects of this invention are as follows: When the power supply vehicle needs to be towed, the towing ring at the end of the towing rod is attached to the towing vehicle, which then tows the power supply vehicle. When the power supply vehicle needs to move on its own, it is driven by the power supply vehicle drive device. Since the steering seat is rotatably mounted at the front of the power supply vehicle, the steering seat is rotated by the towing rod using the operating handle, thus turning the entire power supply vehicle. The operating handle can also be used to drive the power supply vehicle forward or backward. After the power supply vehicle is in position, the braking device applies braking force to the steering wheels, fixing the position of the power supply vehicle. This invention enables the power supply vehicle to be both towed and self-propelled, solving the problems of time-consuming, labor-intensive, and inefficient use of traditional energy storage power supply vehicles.

[0029] The following is in conjunction with the appendix Figure 1 To be continued Figure 7 The present invention will be further described below.

[0030] A self-propelled and traction integrated structure for an energy storage power vehicle includes a power vehicle 1, in which a power source 3 and an energy storage battery pack 4 connected to the power source 3 are installed. It also includes: a power vehicle drive unit for driving the power vehicle 1; a steering seat 11 with steering wheels 12 rotatably mounted at its left and right ends, and a flange 20 rotatably mounted at the upper end of the steering seat 11 via bearing I 19, the flange 20 being fixed to the lower front side of the power vehicle 1; a braking device disposed in the steering seat 11 for generating braking force on the steering wheels 12; a drawbar 6 rotatably mounted at the front end of the steering seat 11 via a shaft II 23; a control handle 8 disposed at the head end of the drawbar 6; and a traction ring 7 disposed at the head end of the drawbar 6. When the power vehicle needs to be towed, the traction ring 7 at the head end of the drawbar 6 is hooked onto a tractor, and the tractor then tows the power vehicle 1. When the power supply vehicle needs to move on its own, the power supply vehicle 1 is driven by the power supply vehicle drive device. At the same time, since the steering seat 11 is rotatably mounted on the front end of the power supply vehicle 1, the steering seat 11 is driven to rotate by the traction rod 6 through the operating handle 8, so as to realize the steering of the entire power supply vehicle 1. The power supply vehicle 1 can also be driven forward or backward by the operating handle 8. After the power supply vehicle 1 moves into position, the braking device generates braking force on the steering wheel 12 to fix the position of the power supply vehicle 1. This realizes that the power supply vehicle can be towed or driven on its own, which solves the problems of time and effort and low work efficiency when using transmission energy storage power supply vehicles.

[0031] The power supply vehicle drive unit can have the following structure: a rear axle 9 mounted on the lower rear side of the power supply vehicle 1 and a motor 10. Drive wheels 2 are mounted on both ends of the rear axle 9. The output shaft of the motor 10 is connected to the input end of the rear axle 9. A motor controller 5 is mounted on the power supply vehicle 1, and the motor 10 is connected to the energy storage battery pack 4 via the motor controller 5. The electrical energy in the energy storage battery pack 4 can be converted by the power supply 3 and supplied to the aircraft, and can also be supplied to the motor 10 driving the rear axle 9 via the motor controller 5. When the motor 10 is powered on, it drives the rear axle 9, causing the drive wheels 2 to rotate, thus enabling the entire power supply vehicle 1 to move.

[0032] The braking device can have the following structure, including a guide groove 21 arranged in the steering seat 11 along the front-rear direction, a brake rod 22 slidably installed in the guide groove 21 and arranged horizontally in the left-right direction, a guide rod I 29 slidably inserted into the steering seat 11 along the front-rear direction, and a push rod 28 installed at the front end of the guide rod I 29. The length of the brake rod 22 is greater than the wheel track between the two steering wheels 12. The rear end of the guide rod I 29 is connected to the brake rod 22. The front end of the spring I 30 is in contact with the brake rod 22, and its rear end is connected to the steering seat 11. When the traction rod 6 rotates to the vertical state, its rear end drives the push rod 28 to move to the rear until the left and right ends of the brake rod 22 are in contact with the wheel surfaces of the corresponding steering wheels 12 on the same side and compress the spring I 30. Once the power supply vehicle 1 is in position, the traction rod 6 is rotated to a vertical position. During this rotation, it drives the guide rod I 29 to slide towards the rear end via the push rod 28. At this time, it pushes the brake rod 22 to move towards the rear end. After the brake rod 22 contacts the steering wheel 12, it achieves braking of the steering wheel 12 by means of friction, which is convenient to operate. When the brake rod 22 tilts forward, the spring I 30 releases its elastic force, thereby pushing the guide rod I 29 forward. At this time, the brake rod 22 moves away from the steering wheel 12, thus releasing the brake.

[0033] Furthermore, it also includes a swing bracket 18, the middle part of which is rotatably mounted on the traction rod 6 via a pivot I 14. A foot pedal 15 is installed at the front end of the swing bracket 18, and a hook 24 is installed at its rear end. A protrusion 25 is installed on the steering seat 11, and a groove is formed between the rear end of the protrusion 25 and the steering seat 11. The rear end face of the hook 24 is a guide slope I 26, and the front end face of the protrusion 25 is a guide slope II 27. When the traction rod 6 rotates to the rear end, the guide slope I 26 of the hook 24 contacts the guide slope II 27 of the protrusion 25, and the hook 24 swings upward. When the traction rod 6 rotates to the vertical position, the hook 24 is located in the groove. As the traction rod 6 rotates to a vertical position, the guide slope I 26 of the hook head 24 comes into contact with the guide slope II 27 of the protrusion 25. Under the guidance of the slope, the swing bracket 18 will rotate counterclockwise through the rotating shaft I 14. When the traction rod 6 rotates to a vertical position, the hook head 24 crosses the protrusion 25. Under the action of gravity, the hook head 24 falls into the slot at the rear end of the protrusion 25. At this time, it ensures that the traction rod 6 is in a vertical position, prevents it from tilting forward, and keeps the braking force of the steering wheel 12 constant.

[0034] Preferably, it also includes a tension spring 17, one end of which is connected to the steering seat 11, and the other end is connected to the traction rod 6. When the tension spring 17 is in a free state, the traction rod 6 is in a vertical state. By setting the tension spring 17, when the traction force on the traction rod 6 is released, the traction rod 6 can be automatically rotated to a vertical state under the action of the tension spring 17, at which time the entire power vehicle 1 is braked, improving the convenience and reliability of use.

[0035] Preferably, the device further includes a rotating box 13 rotatably mounted on the head end of the traction rod 6 via bearing II 36. The operating handle 8 is mounted on the rotating box 13. When the operating handle 8 is rotated to the front end or the rear end, it is locked relative to the traction rod 6 by a locking device. The operating handle 8 can rotate through the rotating box 13. When the operating handle 8 needs to be used, it can be rotated to the front end. When the traction ring 7 is used to traction the entire power vehicle 1, the operating handle 8 is rotated to the rear end to prevent interference when the operating handle 8 tractions the traction ring 7.

[0036] The locking device can have the following structure, including two locking pins 37 that are vertically slidably installed in the rotating box 13, a spring Ⅲ 39 that is fitted onto the locking pins 37, the upper end of the spring Ⅲ 39 being connected to the rotating box 13 and the lower end being connected to the locking pins 37, two locking holes Ⅱ 40 being provided at the front end of the traction rod 6, and two locking holes Ⅰ 38 being provided at the rear end of the traction rod 6. When the operating handle 8 is rotated to the front end, the two locking pins 37 are inserted into the corresponding locking holes Ⅰ 38 under the elastic force of the spring Ⅲ 39. When the operating handle 8 is rotated to the rear end, the two locking pins 37 are inserted into the corresponding locking holes Ⅱ 40 under the elastic force of the spring Ⅲ 39. The upper ends of the two locking pins 37 are connected by a handle 16. When the operating handle 8 needs to be rotated, the two locking pins 37 are pulled out from the locking hole I 38 or locking hole II 40 by the handle 16. Then the rotating box 13 can be rotated. When the operating handle 8 is rotated to the position, the handle 16 is released. Under the elastic force of the spring III 39, the locking pins 37 can be inserted into the corresponding locking hole I 38 or locking hole II 40, realizing the locking after the operating handle 8 is in the position, thus improving the reliability of use.

[0037] Preferably, a guide rod II 31 is slidably inserted into the head end of the traction rod 6 in the horizontal direction. A traction ring 7 is installed at the head end of the guide rod II 31. A boss 35 is installed at the tail end of the guide rod II 31. A partition 32 is installed inside the traction rod 6. The front end of the partition 32 forms a front cavity, and the rear end of the partition 32 forms a rear cavity. A spring II 33 is located in the front cavity and is fitted onto the guide rod II 31. The front end of the spring II 33 is connected to the guide rod II 31, and its rear end contacts the partition 32. Several disc springs 34 are located in the rear cavity and are fitted onto the guide rod II 31. The front end of the disc springs 34 contacts the partition 32, and its rear end contacts the boss 35. When the power supply vehicle 1 is driven, the disc springs 34 are compressed for buffering. When the power supply vehicle 1 brakes, the springs II 33 are compressed for buffering, thereby making the power supply vehicle 1 drive smoothly during traction.

[0038] It may also include a rotary switch 41, which is electrically connected to the motor controller. The rotary switch 41 can control the motor 10 to rotate forward or backward, thereby controlling the entire power vehicle 1 to move forward or backward.
