Description

Technical Field

[0001] The invention relates to the technical field of scooters, in particular to an electric foldable scooter. Background Art

[0002] With the development of the scooter industry, foldable scooters can fold the handle and pedal parts of the scooter, which is more convenient for storage and transportation. Therefore, foldable scooters have become an important direction in the development of scooter technology. For example, the automatic folding electric scooter with announcement number CN112026971B and the variable folding scooter with announcement number CN106564549B. Although the above-mentioned existing foldable electric scooters have a folding function, so that the scooter can be folded to facilitate towing or carrying when not riding, in the modified folding scooter of CN106564549B, the rear wheel adopts a double-wheel structure. Although such a design allows the scooter to touch the ground with three wheels at the same time after folding, which is more conducive to the smooth towing process, due to the design of three wheels, it lacks the flexibility of turning compared with the existing scooters with one wheel at the front and one wheel at the back; and in the automatic folding electric scooter of CN112026971B, the status quo of one wheel at the front and one wheel at the back is retained, but because the front wheel and the rear wheel are located in the same straight line after folding, the scooter is easy to tip to the left or right when towing, which brings inconvenience to towing.

[0003] Therefore, in the electric scooter industry, for electric scooters with one wheel at the front and one wheel at the back, how to make the scooter more stable when folded, so as not to change the flexibility of riding and to have stability during towing after folding, has become an important technical development route in the field of electric scooters. Summary of the invention

[0004] The present invention aims to solve one of the technical problems in the related art at least to a certain extent: to provide an electric foldable scooter, which can enable the scooter to be towed more smoothly after being folded without changing the front and rear wheels of the scooter.

[0005] To this end, an object of the present invention is to provide an electric foldable scooter, which includes an elongated pedal, a front wheel and a rear wheel arranged at both ends of the pedal along the length direction of the pedal, and an operating rod arranged on the pedal for driving the front wheel to steer, the upper end of the operating rod has a handle, and is characterized in that: a connecting piece is provided between the pedal and the operating rod, the operating rod and the connecting piece are rotatably matched, and the front end of the pedal is hinged to the connecting piece so that the pedal has a folded state in which the rear end is close to the operating rod and an unfolded state away from the operating rod, and at least two auxiliary wheels are arranged at intervals in the width direction on the pedal, and the auxiliary wheels are arranged so that the bottom of the auxiliary wheels is flush with the bottom of the front wheel when the pedal is in the folded state, and is suspended above the horizontal plane where the bottom of the front wheel and the rear wheel are located when the pedal is in the unfolded state.

[0006] The above technical solution has the following advantages or beneficial effects: when the operating rod and the pedal are unfolded and in the unfolded state, the operating rod and the pedal are generally in a positional relationship close to a right angle, and the auxiliary wheels are hidden in a position between the front wheel and the front end of the pedal. Since the auxiliary wheels are located above the ground where the front wheel is located at this time, the suspended auxiliary wheels will not interfere with the user's riding, and the rider can still use the existing riding habits of the two-wheeled electric scooter; and when the rider needs to fold the scooter, he only needs to fold the operating rod and the pedal along the hinge point on the connecting piece to a folded state. At this time, the auxiliary wheels swing downward with the swing of the pedal, thereby making the bottom of the front wheel and the two auxiliary wheels flush, and finally the rider can tow the scooter. At this time, since the two auxiliary wheels are arranged at intervals in the width direction, the towing process can be smooth.

[0007] According to an example of the present invention, the connecting member includes a sleeve sleeved outside the operating rod, and a connecting arm with one end fixedly connected to the sleeve, and the other end of the connecting arm is hinged to the front end of the pedal.

[0008] According to an example of the present invention, there are two auxiliary wheels, which are arranged at intervals along the width direction of the pedal, and the auxiliary wheels are located at the end of the hinge between the pedal and the connecting arm close to the front wheel.

[0009] According to an example of the present invention, a bracket is provided between the auxiliary wheel and the pedal, the auxiliary wheel is mounted on one end of the bracket, the other end of the bracket is hinged to the pedal, and the pedal has a locking mechanism for locking the bracket position, so that the bracket has at least two working positions relative to the pedal. The position of the auxiliary wheel can be adjusted by the bracket, so that when the pedal is in the folded state, the auxiliary wheel can change the relative position of the auxiliary wheel and the front wheel by adjusting its own position, so as to meet the use requirements of different scenarios.

[0010] According to an example of the present invention, the locking mechanism includes a limit groove for the bracket to pass through and a tension spring for driving the bracket to move toward an inner side wall of the limit groove at a similar position in the limit groove, and the tension spring drives the bracket to rotate forward or reverse to an extreme position and abuts against the inner wall of the limit groove.

[0011] According to an example of the present invention, a water retaining roller is provided between the two auxiliary wheels, and both ends of the water retaining roller are respectively connected to the auxiliary wheels, and when the pedal is in the unfolded state, the water retaining roller is in contact with the front wheel. The water retaining roller can be in contact with the rear side of the front wheel during the riding of the scooter, thereby playing a role in retaining water.

[0012] According to an example of the present invention, the water retaining roller is in the shape of a waist drum with diameters at both ends larger than the middle diameter, and the outer side surface of the water retaining roller is configured so that the tread of the front wheel remains in contact with the water retaining roller during the steering of the front wheel.

[0013] According to an example of the present invention, the hub of the auxiliary wheel and the water-retaining roller are an integrated structure, and the tire of the auxiliary wheel is sleeved outside the hub.

[0014] According to one example of the present invention, the pedal includes a front pedal and a rear pedal hinged to each other along the length direction, the left end of the front pedal is hinged to the connecting arm, and when the pedal is in a folded state, the right end of the rear pedal is folded downward to be close to the front pedal.

[0015] According to an example of the present invention, a detachable battery is provided in the front pedal, and an opening for loading and unloading the battery is provided at the end of the front pedal facing the rear pedal, and the end of the rear pedal blocks the opening when the pedal is in the unfolded state.

[0016] Additional aspects and advantages of the present invention will be given in part in the following description and in part will be obvious from the following description, or will be learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0027] The main component of a scooter is a pedal for people to step on. The pedal is a long strip with a length direction greater than the width direction. The front end of the pedal is provided with an operating rod that can rotate around its own axis. The operating rod and the pedal are generally L-shaped, and a wheel is provided at the front and rear sections of the pedal respectively. The two wheels are the front wheel and the rear wheel. The front wheel and the operating rod form a linkage, so that the steering of the front wheel is adjusted by the rotation of the operating rod. The above structure is the basic structure of the existing scooter. However, due to the characteristics of the scooter such as light weight, small wheel diameter, and narrow width direction, it is difficult to drag or carry the scooter in a non-riding state. That is, when the operator holds the handle at the upper end of the operating rod to push the scooter during the towing process, the pedal is easily offset and tipped over. During the transportation process, the pedal and the operating rod are L-shaped, so they take up a lot of space and are not conducive to transportation. For this reason, the folding scooter in the prior art has become the mainstream product in the scooter field. The so-called folding of the scooter refers to changing the relative position between the pedal and the operating rod, thereby making the scooter more compact in a non-riding state, thereby bringing convenience to towing and carrying. However, since the existing scooters have one wheel at the front and one wheel at the back, even if the pedals are folded, they are still arranged in the form of front and rear wheels, and the user cannot conveniently tow the folded scooter in the same way as towing a suitcase. When the user tows the existing folding scooter, the front and rear wheels of the scooter are distributed front and back and are located on the same straight line, so the balance between the left and right sides cannot be maintained during towing, which brings inconvenience to the towing action. In addition, the scooter cannot remain still vertically when the user stands. In response to the problems existing in the towing process, ordinary technicians in this field have considered using a multi-wheel approach to improve the problem of left and right instability after folding, that is, the front and / or rear wheels of the scooter adopt a double-wheel structure. However, this will obviously change the riding habit of the scooter with one wheel at the front and one wheel at the back. Therefore, how to make the scooter have a more stable towing after folding without changing the riding habit of the scooter with one wheel at the front and one wheel at the back has become a technical problem that needs to be discussed for folding scooters.

[0028] The electric foldable scooter according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] The present invention provides an electric foldable scooter, as shown in the figure, it comprises a long strip-shaped pedal 1, a front wheel 2 and a rear wheel 3 arranged at both ends of the pedal 1 along the length direction of the pedal 1, and an operating rod 4 arranged on the pedal 1 for driving the front wheel 2 to turn, the operating rod 4 is generally arranged vertically, and the upper end of the operating rod 4 has a handle 5, characterized in that: a connecting member 6 is provided between the pedal 1 and the operating rod 4, the operating rod 4 rotates around its own axis and cooperates with the connecting member 6, the front end of the pedal 1 is hinged to the connecting member 6, so that the pedal 1 has a folded state in which the rear end is close to the operating rod 4 and an unfolded state away from the operating rod 4, at least two auxiliary wheels 7 arranged at intervals in the width direction are provided on the pedal 1, and the auxiliary wheels 7 are arranged so that when the pedal 1 is in the folded state, the bottom of the auxiliary wheels 7 is flush with the bottom of the front wheel 2, and when the pedal 1 is in the unfolded state, it is suspended above the horizontal plane where the bottoms of the front wheel 2 and the rear wheel 3 are located. In this embodiment, when the pedal 1 is in the unfolded state, the pedal 1 is in a horizontal direction as a whole, and the operating rod 4 is substantially perpendicular to the pedal 1. At this time, the bottom of the front wheel 2 and the rear wheel 3 contact the ground to form a horizontal plane, and the auxiliary wheel 7 is located above the horizontal plane, that is, when the front wheel and the rear wheel of the electric scooter roll on the ground, the auxiliary wheel 7 is suspended above the ground, so that the electric scooter still uses the existing riding method of one wheel at the front and one wheel at the back during riding, and there is no need to change the riding habits of people. In the folded state, after the pedal 1 rotates upward and closes with the operating rod 4, the auxiliary wheel 7 can rotate downward with the rotation of the pedal. At this time, the bottom of the auxiliary wheel 7 is flush with the bottom of the front wheel 2, so that the front wheel 2 and the two auxiliary wheels 7 form a three-point support, so that the scooter in the folded state can stand upright on the horizontal ground, and it is also convenient for people to drag or push the scooter to move horizontally on the ground when walking.

[0030] Based on the preference of the above embodiment, the connecting member 6 includes a sleeve 6.1 sleeved outside the operating rod 4, and a connecting arm 6.2 with one end fixedly connected to the sleeve 6.1, and the other end of the connecting arm 6.2 is hinged to the front end of the pedal 1.

[0031] Preferably, if Figure 4 As shown, there are two auxiliary wheels 7, which are arranged at intervals along the width direction of the pedal 1, and as shown in FIG. Figure 5 The auxiliary wheel 7 is located at the end of the hinge O between the pedal 1 and the connecting arm 6.2, close to the front wheel 2. Since the auxiliary wheel and the rear end of the pedal 1 are respectively located on both sides of the hinge O, when the rear end of the pedal 1 swings upward to the folded state, the auxiliary wheel 7 swings downward synchronously until the bottom of the auxiliary wheel 7 is flush with the bottom of the front wheel 2, so that when the front wheel 2 and the auxiliary wheel 7 are placed on the horizontal ground, the scooter in the entire folded state can be kept upright on the horizontal ground.

[0032] like Figure 5-7As shown, a bracket 8 is provided between the auxiliary wheel 7 and the pedal 1, the auxiliary wheel 7 is mounted on one end of the bracket 8, and the other end of the bracket 8 is hinged to the pedal 1. The pedal 1 has a locking mechanism for locking the bracket 8, so that the bracket 8 has at least two working positions relative to the pedal 1. Figure 5 The auxiliary wheel 7 and the bracket 8 are in the first working position, Figure 6 is the second working position. When the auxiliary wheel 7 is in the first working position, the auxiliary wheel 7 is closer to the front wheel 2, so during the towing process, the personnel can more flexibly adjust the towing direction by applying different forces on the operating rod, for example, in a complex environment with many people, the towing direction can be changed more flexibly. When the auxiliary wheel 7 is in the second working position, the auxiliary wheel 7 is farther away from the front wheel 2, so the overall stability is higher, which is convenient for the stability of the scooter during rapid towing and is not easily overturned by external forces. In this embodiment, by adjusting the position of the auxiliary wheel, the electric scooter can not only have a more stable towing effect in the folded state compared with the traditional folding scooter, but also can be adjusted according to different actual towing scenes, so as to meet the use in different towing scenes. Of course, in this embodiment, when the auxiliary wheel 7 is switched between different working positions, the auxiliary wheel 7 needs to be kept in the desired working position, so the role of the locking mechanism is to enable the auxiliary wheel 7 and the bracket 8 to remain in the corresponding working position in the locked state, and to switch between different working positions in the unlocked state.

[0033] Based on the preferred embodiment of the locking mechanism in the above embodiment, specifically, Figure 7 As shown, the locking mechanism includes a limiting groove 9 for the bracket 8 to pass through and a tension spring 10 for driving the bracket 8 to move toward the inner side wall of the groove at a position close to the limiting groove 9. When the tension spring 10 drives the bracket 8 to rotate forward or reverse to the limit position, it abuts against the inner wall of the limiting groove 9. The connection point where the upper end of the tension spring 10 is connected to the pedal 1 is the first point, the connection point where the lower end of the tension spring 10 is connected to the bracket 8 is the second point, and the hinge point where the bracket 8 and the pedal 1 rotate is the third point. The line between the first point and the second point is the tension spring 10 line. In the process of the bracket 8 driving the auxiliary wheel 7 to rotate forward and reverse, the bracket 8 abuts against the inner walls of the groove on both sides of the limiting groove 9 respectively, thereby forming two working positions. When the bracket 8 and the auxiliary wheel 7 are respectively in the two working positions, the tension spring line is respectively located on both sides of the third point. Due to the tension of the tension spring 10, the bracket 8 can exert a movement tendency of the bracket 8 against the inner walls of the adjacent grooves when it is in the two working positions, so that the bracket 8 remains in the current working position.

[0034] Since the bracket 8 rotates around the hinge point between the upper end of the bracket 8 and the pedal 1, all kinds of locking parts in the prior art that play a limiting role for the rotating parts can achieve the locking and unlocking of the bracket 8. For this reason, in this embodiment, the structure of the above-mentioned conventional locking parts with locking and unlocking functions is not described one by one.

[0035] The wheels of existing scooters are generally provided with water shields, which are arranged at the rear of the wheel's forward direction, so as to shield the water splashed by the wheel's rolling. However, in the above embodiment, due to the addition of the auxiliary wheel 7, the space between the front wheel 2 and the pedal 1 is not enough to install a water shield. For this reason, the improvement of this embodiment is that a water shield roller 11 is provided between the two auxiliary wheels 7, and the two ends of the water shield roller 11 are respectively connected to the auxiliary wheels 7. When the pedal 1 is in the unfolded state, the water shield roller 11 fits with the front wheel 2. Since the water shield roller can rotate around its own axis, the tread of the tire of the front wheel 2 can be made to fit with the water shield roller, which not only improves the water shielding effect, but also because the water shield roller 11 is installed between the two auxiliary wheels 7, the water shield plate installed additionally on the front wheel 2 is omitted, making the overall structure more compact.

[0036] Furthermore, the water-blocking roller 11 is in the shape of a waist drum with diameters at both ends larger than the middle diameter, and the outer side of the water-blocking roller 11 is arranged so that the tread of the front wheel 2 is kept in contact with the water-blocking roller 11 during the turning process of the front wheel 2. Figure 4 As shown, the cross section of the outer wall of the water retaining roller 11 is in the shape of a concave arc, and the center of the arc-shaped outer wall coincides with the axis of the front wheel steering, so that the tread of the front wheel 2 can always be kept in contact with the arc-shaped outer wall of the water retaining roller during the steering of the front wheel 2. Thus, the steering of the front wheel 2 is not hindered, and the water retaining roller can play a better water retaining effect after being in contact with the front wheel 2. At the same time, the water retaining roller is located between the two auxiliary wheels, and the water retaining roller and the auxiliary wheel are coaxially installed, so it will not occupy additional space between the front wheel and the pedal, and there is no need to set up additional mounting brackets and bearings, and the overall structure is compact.

[0037] Preferably, the wheel hub 7.1 of the auxiliary wheel 7 and the water-blocking roller 11 are integrated, and the tire 7.2 of the auxiliary wheel 7 is sleeved outside the wheel hub 7.1. The auxiliary wheel 7 can be formed by sleeved an elastic tire on the wheel hub 7.1 and the water-blocking roller 11 and the wheel hub 7.1 of the auxiliary wheel 7.

[0038] like Figure 8As shown, the pedal comprises a front pedal 1.1 and a rear pedal 1.2 which are hinged to each other along the length direction, the left end of the front pedal 1.1 is hinged to the connecting arm 6.2, and when the pedal is in the folded state, the right end of the rear pedal 1.2 is folded downward to be close to the front pedal 1.1. By dividing the pedal 1 into two front and rear plates, the pedal can be folded in half, so that the center of gravity of the pedal is lower, which is conducive to the stability of the towing process, and the rear wheel can be prevented from facing outward after the rear pedal 1.2 is folded downward, so as to prevent the tread of the rear wheel 3 from hitting the clothes of the person.

[0039] Based on the improvement of the above embodiment, a detachable battery 12 is provided in the front pedal 1.1, and an opening for loading and unloading the battery 12 is provided at the end of the front pedal 1.1 facing the rear pedal 1.2, and the end of the rear pedal 1.2 blocks the opening when the pedal 1 is in the unfolded state. That is, the front pedal 1.1 has an installation cavity for installing the battery 12, and the opening for loading and unloading the battery 12 on the installation cavity is arranged at the end of the front pedal 1.1 facing the rear pedal 1.2, so that when the pedal is in the unfolded state, the adjacent ends of the front pedal 1.1 and the rear pedal 1.2 are docked, so that the opening is closed. When the pedal 1 is in the unfolded state, the front pedal 1.1 and the rear pedal 1.2 are docked, so that the opening is closed. Figure 8 In the folded state shown, the ends of the front pedal 1.1 and the rear pedal 1.2 are folded and opened, so that the openings are exposed.

[0040] It should be understood that when the pedal is in the folded state, a connecting member is allowed to be provided between the pedal and the operating rod to keep the pedal and the operating rod in the folded state. Figure 8 In the folded state shown, a connecting component may be provided between the front pedal 1.1 and the rear pedal 1.2 for keeping the front pedal 1.1 and the rear pedal 1.2 in the folded state.
