Description

Technical Field

[0001] The invention relates to the technical field of transport tools, in particular to an improved clamping type electric bicycle moving device. Background Art

[0002] With the breakthrough of key technologies in my country's electric bicycle industry and the continuous improvement of the performance of core components, electric bicycles have gradually become a substitute for motorcycles and bicycles due to their advantages such as environmental protection, convenience and speed, and have been recognized and favored by many consumers in my country. More and more consumers choose electric bicycles as the first choice for convenient riding tools for short-distance urban transportation. At present, my country has developed into the world's largest producer, consumer and exporter of electric bicycles. According to data, the number of electric bicycles in my country in 2021 has exceeded 320 million. While bringing convenience to the people, the huge number of electric bicycles has also brought congestion problems to urban traffic and parking. Especially in large and medium-sized cities, a large number of electric bicycles are often parked in parking lots and roadsides in crowded places such as shopping malls, theaters, residential communities, and subway entrances. Some electric bicycles that are not parked in order have brought huge management pressure to parking lot managers and traffic police departments. Especially for some overweight electric bicycles and even electric motorcycles that are parked randomly, if manpower is used to drag, transport, sort and sort, it will not only be time-consuming and labor-intensive, but may even cause damage to the locked electric bicycles.

[0003] The prior art discloses a portable electric vehicle moving device with a patent application number of 201810658418X, and its technical solution includes: rollers are provided at both ends of the steel frame, and a U-shaped tripod is provided at one end, and a fixing device for the U-shaped support leg of the electric vehicle is also provided on the tripod, and a rotation limit device is provided on the tripod and the steel frame. The above technical solution utilizes the lever structure on the original U-shaped support leg of the electric vehicle to set up the moving device on the bottom of the electric vehicle by manpower, so that the rear wheel of the electric vehicle is off the ground and the vehicle is moved with the universal wheels on the steel frame. After the vehicle is moved into place, it is necessary to pull the pull ring back and lift the steel frame by manpower. After the front wheel of the electric vehicle touches the ground, the brake of the universal wheel is stepped on, and the U-shaped support leg of the electric vehicle is retracted to make the rear wheel of the electric vehicle touch the ground, and finally the fixing device is removed from the U-shaped support leg of the electric vehicle. It can be seen that this solution requires manpower to retract and extend the U-shaped legs of the electric vehicle to set up the steel frame of the car mover. The steps for using the car mover are relatively complicated and the efficiency of moving the car is low. It is only suitable for the semi-manual moving needs of a small number of randomly parked electric bicycles. Summary of the invention

[0004] The purpose of the present invention is to propose an improved clamping type electric bicycle moving device technical solution in view of the shortcomings and deficiencies of the above-mentioned portable battery bicycle moving device design, so as to solve the problems that the above-mentioned portable battery bicycle moving device relies on manpower to place the steel frame and the operation steps are relatively complicated, and is not suitable for the labor-saving moving needs of a large number of disorderly parked electric bicycles.

[0005] To achieve the above-mentioned purpose, the present invention can adopt the following technical scheme: the main structure of the clamping type electric bicycle moving device described in the present invention mainly includes a body base and a body front arm that can bear a load, a body frame equipped with a slider box, a front fork installed in the slider box, and a towing clamp for clamping and lifting the electric bicycle.

[0006] Furthermore, the body base and the bottom of the body front arm of the clamping type electric bicycle moving device are arranged with universal wheels that can be flexibly turned and moved.

[0007] Furthermore, a body frame is arranged on the upper part of the body base of the clamping type electric bicycle moving device, and a vertical slide bar and a vertical screw are vertically installed on the body frame. The slider box is assembled on the vertical slide bar and the vertical screw in the body frame, and the slider box can move vertically up and down.

[0008] Furthermore, a horizontal slide bar and a horizontal lead screw are horizontally installed inside the slider box opening of the clamping type electric bicycle moving device, two front forks with adjustable spacing left and right are forwardly installed on the horizontal slide bar and the horizontal lead screw in the slider box, and a supporting clamp for lifting the electric bicycle is connected to the front end of the front fork.

[0009] Furthermore, a control panel is installed on the upper part of the body frame of the clamping type electric bicycle mover, handlebars and grip covers for push-pull shifting are installed on both sides, and a battery that can provide a power source is arranged at the lower part of the body frame.

[0010] Compared with the existing electric bicycle moving device, the advantages of the present invention are that the technical solution of the improved clamping type electric bicycle moving device is simple in structure, ingenious and reasonable in design, and has high moving efficiency. The improved clamping type electric bicycle moving device adopts a battery power source to drive the stepping motor to drive the lead screw to rotate, so as to realize the vertical up and down movement of the slider box and the towing clamp and the horizontal clamping and releasing action of the towing clamp. The operation steps are simple and easy to use, which improves the weakness of the traditional electric bicycle moving device with many operation steps and mainly relying on manual operation, and can effectively solve the problem that it takes time and effort for managers to move vehicles when a large number of electric bicycles are parked in disorder.

DETAILED DESCRIPTION

[0019] The specific implementation of the technical solution of the present invention is further described below in conjunction with the accompanying drawings.

[0020] The improved clamping electric bicycle moving device of the present invention is mainly applicable to the field of handling equipment and tool technology. In particular, the invention is aimed at a large number of disorderly parked electric bicycles. The battery 5 is used as power to clamp and lift the rear wheel or front wheel of the locked electric bicycle, which can quickly and easily complete the moving and sorting of the bicycles, and has universal adaptability. Figure 1 , Figure 2 , Figure 3 , Figure 4It can be clearly seen that the clamping type electric bicycle moving device is composed of several main components, such as a body base 1 and a body front arm 3 that can bear a load, a body frame 2 equipped with a slider box 10, a front fork 11 assembled in the slider box 10, and a towing clamp 12 for clamping and lifting the electric bicycle.

[0021] from Figure 1 , Figure 2 , Figure 3 , Figure 4 It can be clearly seen that the front end of the body base 1 of the clamping type electric bicycle moving device is connected to a finger-type body front arm 3 on the left and right sides respectively, and four flexibly steerable and movable universal wheels 4 are arranged at the four corners of the body base 1 and the bottom of the two body front arms 3. A square frame 2 and a battery 5 for powering a control panel 15, a vertical stepping motor 8, and a horizontal stepping motor 9 are vertically fixedly installed on the upper part of the body base 1. A handlebar 6 of the moving device that can be used for hand-held pushing and pulling and a grip cover 7 for easy gripping are horizontally installed on the upper part of the body frame 2. A control panel 15 is installed between the upper part of the body frame 2 and the handlebar 6 of the moving device. There are buttons on the control panel 15 corresponding to the forward and reverse rotation of the vertical stepping motor 8 and the horizontal stepping motor 9 respectively. The forward and reverse rotation of the vertical stepping motor 8 and the horizontal stepping motor 9 can be realized by using the corresponding buttons on the control panel 15 and cooperating with the simple circuit in the control panel 15.

[0022] Combination Figure 2 , Figure 3 , Figure 4 It can be clearly seen that a rotatable vertical screw 17 is vertically installed in the middle of the body frame 2 of the clamping type electric bicycle moving device, and two cylindrical vertical slide bars 16 are vertically fixedly installed on the left and right sides. The vertical screw 17 and the vertical slide bar 16 are cooperated with a slider box 10 that can move vertically up and down, and a vertical stepping motor 8 is installed on the upper part of the body frame 2 for driving the vertical screw 17 to rotate.

[0023] from Figure 4 , Figure 5 , Figure 6 , Figure 7 It can be clearly seen that a rotatable horizontal lead screw 19 is installed in the horizontal middle position of the front end opening of the slider box 10 of the clamping type electric bicycle moving device, and two cylindrical horizontal slide bars 18 are horizontally fixedly installed on the upper and lower sides. A horizontal stepping motor 9 for driving the horizontal lead screw 19 to rotate is installed on the side of the slider box 10, and two front forks 11 with horizontally adjustable spacing left and right and matching bicycle support clamps 12 are installed on the horizontal lead screw 19 and the horizontal slide bar 18.

[0024] Combination Figure 4 , Figure 5 , Figure 6 , Figure 7It can be clearly seen that a vertical screw nut 21 which passes vertically up and down and can cooperate with the vertical screw 17 is provided in the middle of the slider box 10 of the clamping type electric bicycle moving device, and two vertically passing vertically up and down vertical slide bar limiting cylinders 20 which can cooperate with the vertical slide bar 16 are respectively provided on the left and right sides. The vertical slide bar limiting cylinders 20 cooperate with the vertical slide bar 16 to ensure that the slider box 10 can only move up and down with the forward and reverse rotation of the vertical screw 17.

[0025] from Figure 4 , Figure 5 , Figure 6 It can be clearly seen that one end of the horizontal lead screw 19 on the left and right sides is a positive thread, and the other end is a negative thread, that is, the horizontal lead screw 19 is a positive and negative thread bidirectional spiral lead screw. The two front forks 11 assembled in the front end opening of the slider box 10 are each provided with a horizontal lead screw nut 23 that can cooperate with the horizontal lead screw 19, and each front fork 11 is provided with two horizontal slide bar limiting cylinders 22 that can cooperate with the horizontal slide bar 18 on the upper and lower sides. The horizontal slide bar limiting cylinders 22 cooperate with the horizontal slide bar 18 to ensure that as the horizontal lead screw 19 rotates forward and reverse, the two front forks 11 are clamped or released at the same time in the horizontal direction.

[0026] from Figure 1 , Figure 2 , Figure 3 It can be clearly seen that the front ends of the two front forks 11 of the clamping type electric bicycle moving device are respectively connected to the supporting clamps 12 for lifting the electric bicycle, and the upper part of the supporting clamp 12 is provided with three semicircular grooves of different radius sizes to accommodate electric wheel axle nuts 14 of different sizes, and limiting blocks 13 are respectively provided at the front and rear ends of the upper part of the supporting clamp 12 to prevent the electric bicycle wheel from accidentally falling out of the supporting clamp 12 during the clamping, carrying and moving process.

[0027] The working principle of the clamping type electric bicycle moving device is further described below in conjunction with the accompanying drawings.

[0028] from Figure 1 , Figure 2 , Figure 3 , Figure 4It can be clearly seen that the four universal wheels 4 arranged at the bottom of the vehicle body base 1 and the two vehicle body front arms 3 can ensure that the clamping type electric bicycle moving device can achieve flexible steering and movement. The slider box 10 of the clamping type electric bicycle moving device and the matching vertical screw 17, vertical screw nut 21, horizontal screw 19, horizontal screw nut 23 and other structures are the key to ensure that the clamping type electric bicycle moving device of the present invention can not only vertically move up and down to adjust the height of the slider box 10, the front fork 11 and the towing clamp 12, but also adjust the distance between the two towing clamps 12 left and right. In the initial state before moving the vehicle, the slider box 10 of the clamping type electric bicycle moving device is at a lower position of the vertical screw 17, and the two front forks 11 and the towing clamps 12 are in a left and right loose position with a larger distance in the middle.

[0029] Further, from Figure 1 , Figure 2 , Figure 3It can be clearly seen that when a target electric bicycle with a rear wheel locked and parked in disorder needs to be moved, the manager firstly holds the grip cover 7 of the handlebar 6 of the bicycle mover, aligns the center position of the two body front arms 3 of the clamping electric bicycle mover with the rear of the target electric bicycle, and gradually pushes it from the back to the front, until the semicircular grooves in the middle of the two bicycle holders 12 are roughly aligned with the electric wheel axle nuts 14 on the upper left and right sides respectively from the bottom. At this time, the vertical stepping motor 8 drives the vertical lead screw 17 to rotate forward through the corresponding button on the control panel 15, and the vertical lead screw 17 and the vertical lead screw nut 21 cooperate with each other to realize the vertical upward movement of the slider box 10, the front fork 11 and the two bicycle holders 12. Conversely, when the vertical stepping motor 8 drives the vertical lead screw 17 to rotate in the opposite direction, the vertical downward movement of the slider box 10, the front fork 11 and the two bicycle holders 12 can also be realized. When the two vehicle support clamps 12 at the front end of the front fork 11 gradually approach the electric wheel axle nut 14 from bottom to top, the horizontal stepping motor 9 drives the horizontal lead screw 19 to rotate forward through the corresponding button on the control panel 15. Because the horizontal lead screw 19 is a bidirectional helical lead screw with positive and negative teeth, the horizontal clamping action of the two vehicle support clamps 12 can be achieved under the mutual cooperation of the horizontal lead screw 19 and the horizontal lead screw nut 23. Conversely, when the horizontal stepping motor 9 drives the horizontal lead screw 19 to rotate in the opposite direction, the horizontal loosening action of the two vehicle support clamps 12 can also be achieved. The manager visually observes the position of the electric wheel axle nut 14, and fine-tunes the position of the clamping type electric bicycle moving device again through the handlebar 6 of the moving device, and adjusts the vertical height position of the two towing clamps 12 and the horizontal tightness position of the two towing clamps 12 through the corresponding buttons on the control panel 15 for many times, until the two towing clamps 12 just clamp the electric wheel axle nuts 14 at both ends of the rear wheel horizontally from both sides, that is, the electric wheel axle nuts 14 at both ends are just located in the semicircular grooves of the two towing clamps 12. Next, the vertical stepping motor 8 drives the vertical lead screw 17 to continue to rotate forward, so that the two towing clamps 12 continue to move vertically upward, and finally the rear wheel of the locked electric bicycle is clamped and lifted to a certain appropriate height. At this time, the grip cover 7 of the handlebar 6 of the moving device can be held by hand, and the universal wheel 4 can be conveniently used to move the electric bicycle moving device that clamps the rear wheel of the electric bicycle in any direction, so as to quickly and conveniently realize the moving of the target electric bicycle.

[0030] Compared with several traditional electric bicycle moving devices, the clamping electric bicycle moving device has a simple structure and is more labor-saving, convenient and efficient. If the front wheel of the target electric bicycle is locked, the clamping electric bicycle moving device can be used to clamp and lift the locked front wheel. If the front wheel and the rear wheel are locked at the same time, two clamping electric bicycle moving devices can be used at once to clamp and lift the locked front wheel and rear wheel at the same time, so that the disorderly parked electric bicycle can be moved conveniently. Therefore, the clamping electric bicycle moving device has strong adaptability.
