Description

Technical Field

[0001] The present invention relates to the technical field of trolleys, and more particularly to an electric passenger trolley. Background Art

[0002] The electric carts used in the market use hub motors, supporting batteries, throttle switches and other accessories to form an electrically controlled flatbed cart. It can solve the problem of operators having difficulty in pushing the cart due to the heavy weight of the transported items.

[0003] However, there are also some problems in the use of electric carts: the speed of the hub motor is controlled by the throttle switch. Although the speed can be adjusted faster or slower, it is difficult to achieve synchronous speed compared with the following speed of the operator; in this way, either the hub motor speed is constantly adjusted, and the operation control needs to be sometimes fast and sometimes slow, which increases the jerking feeling of the cart; or the operator changes his own following speed, and the operator's following speed is not the rhythmic speed of his own walking. At the same time, if you want to improve work efficiency and increase the walking speed of the electric cart, the operator's following speed will exceed his own walking speed. Over time, he will inevitably feel tired.

[0004] When an electric cart is moving, if it needs to stop, it needs to automatically slow down and travel a certain distance before it can reach a stationary state. Because the parking process has a delay, if it exceeds the expected situation, when an emergency occurs, it will be impossible to handle it and it is easy to cause an accident; for this reason, we propose an electric manned cart.

[0017] The manned step is designed with a single-point connection, so that when the manned step carries the operator, the operator can push the electric trolley left and right through the handrail, and the electric trolley can swing left and right following the thrust; this can solve the problem that when the electric trolley drags the operator to walk, the electric steering is not sensitive enough, and the front of the trolley deviates from the position expected by the operator;

[0018] The energy recovery braking method can increase the controllable operation of the electric car's walking speed. When the operator stops the given speed, the car will automatically slow down and stop. Especially when the load is heavy, the overall mass inertia of the car is large. Through energy recovery braking, the car can be decelerated smoothly and stopped in a short distance. It solves the problem that when the car stops naturally, it must travel a long distance to consume its own energy to stop. This can reduce many unsafe factors in the parking process.

[0028] The present invention is described in detail below in conjunction with the accompanying drawings and embodiments.

[0029] like Figure 1-5 As shown, the present invention provides an electric manned trolley, comprising: a load-bearing plate 1 for placing goods, a driving mechanism 2 for driving the load-bearing plate 1, a handrail 3, a manned pedal 4, a folding connector 5, and a control mechanism 6; the driving mechanism 2 is mounted on the lower end surface of the load-bearing plate 1; the handrail 3 is foldably mounted on one end of the upper end surface of the load-bearing plate 1; the control mechanism 6 is mounted on the handrail 3 and is electrically connected to the driving mechanism 2; the manned pedal 4 is rotatably mounted on one end of the load-bearing plate 1 close to the handrail 3 through the folding connector 5; the manned pedal 4 is provided with a walking mechanism 7 and a brake mechanism 8 for braking the walking mechanism 7; the handrail 3 is provided with an elastic rope 9 for hanging the manned pedal 4 on the handrail 3.

[0030] In this embodiment, if Figure 1-3As shown, by providing a manned pedal 4, the manned pedal 4 is connected to one side of the carrying plate 1 of the electric trolley by using a folding connecting piece 5, and the manned pedal 4 drives the operator to walk with the electric trolley through the walking mechanism 7, so that the operator and the electric trolley move synchronously together, so as to solve the existing problem that the speed of the electric trolley is too fast and the operator's walking speed cannot keep up, or the speed of the electric trolley is too slow and the work efficiency cannot keep up, or even the speed of the electric trolley is the same as the walking speed of the operator, and the problem of difficulty in operation due to the problem of the moving speed of the electric trolley is that the folding connecting piece 5 and the elastic rope 9 are used to fold the manned pedal 4 and bind it to the handrail 3, so that when the operator uses the electric trolley as an ordinary trolley, the manned pedal 4 can be prevented from affecting the standing position of the operator, which is convenient for the operator to push the trolley; and the manned pedal 4 can also be turned over and folded on the carrying plate 1 together with the handrail 3 to complete the overall rapid storage work, so that the operator can store and carry it.

[0031] Furthermore, the control mechanism 6 includes: a controller, a battery, a throttle finger switch 61, and a steering finger switch 62; a battery compartment 10 is provided in the middle of the lower end surface of the carrier plate 1; the battery and the controller are both installed in the battery compartment 10; the controller is respectively connected to the drive mechanism 2, the throttle finger switch 61, the steering finger switch 62 and the battery electrical signal; the throttle finger switch 61 and the steering finger switch 62 are both installed on the armrest 3

[0032] Furthermore, the driving mechanism 2 includes: two wheel hub motors 21 and two universal wheels 22; the two wheel hub motors 21 are symmetrically mounted on the lower end surface of the supporting plate 1 close to the armrest 3; the two universal wheels 22 are symmetrically mounted on the lower end surface of the supporting plate 1 away from the armrest 3; the two wheel hub motors 21 are respectively connected to the throttle finger switch 61 and the steering finger switch 62 through the controller.

[0033] In this embodiment, if Figure 1-5As shown, the wheel hub motor 21 adopts mature technical products on the market, which belongs to the existing technology and will not be described in detail here; the controller can be a single-chip microcomputer, MCU, PLC or other controller that can control the orderly operation of electrical components. In this embodiment, MCU is selected; when working, the operator manually presses the throttle finger switch 61 to control the wheel hub motor 21 to start, and then drives the load-bearing plate 1 and the manned pedal 4 to move synchronously through the wheel hub motor 21; when the electric trolley needs to be stopped, the operator controls the wheel hub motor 21 to stop the driving mode through the throttle finger switch 61. At this time, the wheel hub motor 21 will reverse to form a power generation braking mode, converting the kinetic energy of the motor into electrical energy. In addition to producing an electronic braking effect, it can also reverse the energy back to the battery end to charge the battery; and during use, the operator can control the steering finger switch 62 to let the two wheel hub motors 21 move forward at different speeds. When the wheel hub motor 21 is turned on, the electric trolley will make a circular motion around a point on the central axis of the wheel hub motor 21 to achieve a steering effect; after the operator releases the steering finger switch 62, the wheel hub motor 21 returns to a straight-line driving state; the differential steering relies on the wheel hub motor 21 to provide steering power, and does not require human intervention, further reducing the burden on personnel; the overall structure adopts an energy recovery braking method, which can increase the controllable operation of the electric trolley's walking speed. When the operator stops the given speed, the electric trolley will automatically and quickly reduce the speed and stop the car; especially when the mass of the load is large, the overall mass inertia of the electric trolley is large. Through energy recovery braking, the electric trolley can be decelerated smoothly and the parking effect can be achieved within a short distance; the problem that the electric trolley must travel a long distance to consume its own energy before stopping when it stops naturally is solved, which can reduce many unsafe factors in the parking process.

[0034] Furthermore, the folding connecting member 5 includes: a curved arm 51, a fixing seat 52, a connecting seat 53, a first screw rod 54, a second screw rod 55, and a U-shaped member 56; one end of the curved arm 51 is fixedly connected to the passenger pedal 4, and the other end is fixedly connected to the U-shaped member 56; the fixing seat 52 is fixedly mounted on one end of the carrier plate 1 close to the hub motor 21; a mounting groove is provided on the fixing seat 52; one end of the connecting seat 53 is rotatably mounted in the mounting groove through the first screw rod 54 and a nut, and the other end is rotatably mounted in the U-shaped groove of the U-shaped member 56 through the cooperation of the second screw rod 55 and a nut; the first screw rod 54 and the second screw rod 55 are arranged in a cross state; specifically, as Figure 1-5 As shown, in the folding connecting member 5, through the cooperation of the fixing seat 52 and the connecting seat 53, the crank arm 51 can be swung left and right, and folded up and down, thereby driving the manned pedal 4 fixedly connected to the crank arm 51 to swing left and right, and flip up and down.

[0035] Furthermore, the passenger pedal 4 includes: a support frame 41 and two pedal boards 42; the support frame 41 is fixedly connected to the crank arm 51; and the two pedal boards 42 are fixedly mounted on the support frame 41 in a facing state.

[0036] Furthermore, the walking mechanism 7 includes: a rotating shaft 71 and two walking wheels 72; the two walking wheels 72 are rotatably mounted on both sides of the secondary transverse frame through the rotating shaft 71.

[0037] Furthermore, the brake mechanism 8 includes: two brake pads 81, a square rod 82, a brake pedal 83, and two tension springs 84; the middle end of the brake pedal 83 is rotatably mounted on the support frame 41 by a screw rod, and is located in the gap between the two pedals 42; one end of the brake pedal 83 is at a higher level than the two pedals 42, and the other end passes through the gap between the two pedals 42 and is fixedly connected to the square rod 82; the square rod 82 is located below the support frame 41; the two brake pads 81 are respectively fixedly mounted on the two ends of the square rod 82, and are respectively located on one side of the two walking wheels 72; the friction ends of the two brake pads 81 can respectively abut against the two walking wheels 72; one end of the two tension springs 84 is respectively fixedly connected to the support frame 41; the other ends of the two tension springs 84 are respectively fixedly connected to the two ends of the square rod 82.

[0038] In this embodiment, if Figure 1-5As shown, the passenger pedal 4 is connected and installed on the passenger pedal 4 of the electric trolley through a folding connection piece 5, and can realize horizontal swing and vertical up and down swing; the passenger pedal 4 is designed by a single-point connection, so that when the passenger pedal 4 carries an operator, the operator can push the electric trolley left and right through the handrail 3 of the electric trolley, and the electric trolley can swing left and right following the thrust; this can solve the problem that when the electric trolley drags the operator to walk, the electric steering pointing sensitivity is insufficient, and the direction of the vehicle head deviates from the position expected by the operator; the operator stands on the pedal, follows the electric trolley to move forward electrically, and slightly swings the handrail 3 to fine-tune the steering direction of the electric trolley, thereby playing a way of accurately controlling the direction of travel; at the same time, the passenger pedal 4 can be flipped upwards. When the electric trolley is converted to the manual pushing mode, the manned pedal 4 can be flipped up to the position of the handrail 3, and the manned pedal 4 can be bound to the position of the handrail 3 through the elastic rope 9. This can solve the problem that when the operator uses the electric trolley as an ordinary trolley, the towed manned pedal 4 blocks the operator's standing position. When the manned pedal 4 is folded, it is more convenient to push; when the electric trolley is converted to the conveying and folding mode, the handrail 3 of the electric trolley will be folded onto the surface of the carrying plate 1, and the manned pedal 4 will also follow the handrail 3 and flip up onto the surface of the carrying plate 1 together, so as to quickly complete the overall storage work; this can solve the problem that when the electric trolley needs to be transported, either the pedal occupies too much space or the disassembly and assembly of the pedal increases the workload;

[0039] like Figure 1-5 As shown, a brake pedal 83 is provided in the middle of the manned pedal 4, and the brake pedal 83 is linked to the position of the brake pads 81 of the two running wheels 72 of the pedal. By stepping on the brake pedal 83 with the foot, the brake brackets of the two running wheels 72 can drive the brake pads 81 to brake the running wheels 72; when the foot leaves the brake pedal 83, the mechanism will reset the brake pedal 83 through the brake tension spring 84, so that the brake pads 81 are separated from the running wheels 72; the problem of insufficient braking force or unreliable braking effect during the walking and parking process of the electric trolley can be solved; the braking of the running wheels 72 of the manned pedal 4 will be linked to the front end to generate corresponding braking force for the electric trolley, so that when the electric trolley needs a braking effect, in addition to the electric energy recovery braking, there can also be a mechanical braking effect, which has a double protection effect.

[0040] Furthermore, the armrest 3 includes: three cross bars 31 and a U-shaped frame 32; the U-shaped frame 32 can be folded and installed on the bearing plate 1; the two cross bars 31 are sequentially mounted on the U-shaped frame 32 from top to bottom; the throttle finger switch 61 and the steering finger switch 62 are both mounted on the U-frame; specifically, by providing three cross bars 31, the structural strength of the armrest 3 can be further enhanced.

[0041] Furthermore, the elastic rope 9 is installed on the U-shaped frame 32 .

[0042] Furthermore, anti-slip grooves 11 are provided on the end surface of the load-bearing plate 1 to prevent the goods placed on the load-bearing plate 1 from slipping.

[0043] The electric manned trolley of the present invention is provided with a manned pedal 4, and the manned pedal 4 is connected to one side of the carrying plate 1 of the electric trolley by using a folding connecting piece 5. The manned pedal 4 drives the operator to walk with the electric trolley through a walking mechanism 7, so that the operator and the electric trolley move synchronously together, thereby solving the existing problem that the speed of the electric trolley is too fast and the operator's walking speed cannot keep up, or the speed of the electric trolley is too slow and the work efficiency cannot keep up, or even the speed of the electric trolley is the same as the walking speed of the operator, and the problem of difficulty in operation due to the problem of the moving speed of the electric trolley is large; at the same time, the manned pedal 4 is folded and bound to the handrail 3 by cooperating with the folding connecting piece 5 and the elastic rope 9, so that the manned pedal 4 can be easily moved. The manned pedal 4 can be turned over and folded on the carrying plate 1 together with the handrail 3 to complete the overall quick storage work, so that the operator can store and carry it; the manned pedal 4 is designed with a single-point connection, so that when the manned pedal 4 carries the operator, the operator can push the electric trolley left and right through the handrail 3 of the electric trolley, and the electric trolley can swing left and right following the thrust; in this way, the problem of insufficient electric steering sensitivity and deviation of the front direction from the position expected by the operator can be solved when the electric trolley drags the operator to walk.

[0044] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
