Abstract
Description
Technical Field
[0001] This invention relates to the field of electric scooter technology, specifically a stable three-wheeled electric scooter. Background Technology
[0002] The scooter's structure mainly consists of a foot pedal, a front wheel bracket, two front wheels, a rear wheel bracket, and two rear wheels. When in use, one foot is on the foot pedal, and the other foot generates friction with the ground to propel the scooter forward. When the scooter is turning, the two front wheels are not flexible, causing the rider's center of gravity to shift, making it easy to tip over and fall. A solution is needed to address the above-mentioned technical problems.
[0003] As described in the patent document with publication number CN207389402U, this device consists of a right rocker arm, a right pull rod, a rotating component, a rotating spindle, a support base, a left pull rod, and a left rocker arm forming a steering system. The starter motor drives the front drive wheel to rotate, causing the vehicle to glide forward. The steering of the vehicle is controlled by the handlebar assembly. When gliding, pressing the foot pedal tilts the foot pedal, causing the rotating component to deflect around the rotating spindle. The right and left rocker arms deflect around the rotating component simultaneously. The steering system automatically forms a steering curvature at the turning point, making the vehicle more flexible and reliable when turning.
[0004] However, when users drive the device on bumpy roads, the control handle will vibrate violently, reducing the stability of the user's operation and easily causing traffic accidents. At the same time, when users drive the device in winter, their legs are easily affected by cold wind, and the seat may become damp or covered in snow, affecting the user's driving experience. In summer, during long-term driving, users are in a sitting position for a long time, and the parts of the user in contact with the seat are not ventilated for a long time, which can easily cause injury to the body. Summary of the Invention
[0005] The technical problem that this solution addresses is:
[0006] (1) How to solve the problem that during long driving periods in summer, the part of the user in contact with the seat is not ventilated for a long time, which can easily cause damage to the body;
[0007] (2) How to solve the problem that when users drive in winter, their legs are easily affected by cold wind, and the seat is damp or covered with snow, which affects the user's driving experience;
[0008] (3) How to solve the problem that when driving on bumpy roads, the control handle will vibrate violently, which reduces the stability of the user's operation and is prone to traffic accidents.
[0009] The objective of this invention can be achieved through the following technical solution: a stable three-wheeled electric scooter, comprising an electric scooter body and a control rod disposed on one side thereof, a support frame fixedly mounted on the top of one end of the electric scooter body, and a shock-absorbing sleeve for cushioning the control rod fixedly mounted on the other end of the electric scooter body, the shock-absorbing sleeve being prior art; an adjustment mechanism for adjusting the rotation angle of the control rod movably disposed on the top of the control rod; a blower mechanism for improving user comfort is disposed on the side wall of the shock-absorbing sleeve; and a shielding mechanism for preventing the support frame from getting wet in the middle of the top surface of the electric scooter body is movably disposed.
[0010] The blower mechanism includes an air tank fixedly connected to a shock-absorbing sleeve via a connecting plate. A piston is slidably mounted on the inner wall of the air tank, and a push rod is fixedly mounted on the top of the piston. The top of the push rod movably passes through the air tank and is fixedly mounted with a baffle. A first flexible hose is fixedly inserted into the bottom of the air tank, and one end of the first flexible hose is provided with a seat unit for supporting the user. When driving on bumpy roads, the control lever is in a vibrating state. The push plate, in conjunction with the baffle, drives the push rod to move. The piston reciprocates under the action of the thrust spring and the push rod, thereby changing the air pressure in the air tank. This also changes the air pressure in the storage box. When the air in the storage box is forced into the exhaust channel, it ventilates the part of the user that is in contact with the sponge seat, preventing injury to the body. When the air in the exhaust channel is drawn into the storage box, it is dried by a desiccant, thereby ensuring the dryness of the sponge seat and improving the user's comfort.
[0011] A further technical improvement of the present invention is that: the stool unit includes a storage box connected to one end of the first hose, the storage box contains a sufficient amount of desiccant, and the bottom of the storage box is elastically connected to the support frame through several shock-absorbing springs. A sponge stool is glued to the top of the storage box, and several longitudinally arranged exhaust channels are opened inside the sponge stool. Several connecting pipes are fixedly inserted into the top of the storage box.
[0012] A further technical improvement of the present invention is that: a plurality of the connecting pipes are respectively inserted into a plurality of exhaust channels, and the length of the connecting pipes extending into the exhaust channels is one-tenth of the depth of the exhaust channels.
[0013] A further technical improvement of the present invention is that: a limiting sleeve is movably sleeved on the outer wall of the push rod near the baffle, a push plate is fixedly installed on the limiting sleeve, and a thrust spring is elastically arranged between the top of the piston and the inner wall of the gas storage tank.
[0014] A further technical improvement of the present invention is that the shielding mechanism includes two rotating seats fixedly connected to the electric scooter body, and an L-shaped shield is rotatably arranged between the two rotating seats. A first airbag for covering the top surface of the sponge seat is fixedly arranged on the top inner wall of the L-shaped shield. A second hose is connected to the first airbag, and one end of the second hose passes through the L-shaped shield. When the device is not used in winter, the sponge seat is covered by the L-shaped shield, and the first airbag fits the top of the sponge seat completely without any blind spots, improving the protection efficiency of the sponge seat and preventing rainwater and snow from accumulating on the sponge seat, thus preventing any impact on the user's driving experience. When driving the device, by flipping the L-shaped shield and stepping on it with the user's feet, the L-shaped shield comes into contact with the support bar. At this time, the air in the second airbag is squeezed into the first airbag, and the inflated first airbag wraps around the user's legs, not only preventing the user's legs from being affected by cold wind, but also preventing them from being injured by collisions.
[0015] A further technical improvement of the present invention is that: a support bar for limiting the flipping angle of the L-shaped shield is fixedly installed on the electric scooter body, and a second airbag is fixedly installed on the electric scooter body between the support bar and the two rotating seats. The second airbag is filled with sufficient air, and the second airbag is connected to one end of the second hose.
[0016] A further technical improvement of the present invention is that: the adjustment mechanism includes a sliding sleeve movably sleeved on the top of the control rod, and sliding grooves are provided on both inner walls of the sliding sleeve. A slider is slidably disposed inside the sliding groove, and both sliders are fixedly connected to the control rod. The push plate is fixedly connected to the control rod, and a push-pull spring is fixedly connected between the push plate and the sliding sleeve. The push-pull spring provides shock absorption to the sliding sleeve, and the sliding groove limits the slider, so that the operating handle is subjected to less vibration while adjusting the rotation angle of the control rod, making it easier for the user to grip the operating handle, improving the stability of its operation, and avoiding traffic accidents.
[0017] A further technical improvement of the present invention is that an L-shaped frame is fixedly installed on the outer wall of the sliding sleeve, and an operating handle is fixedly connected to the top of the L-shaped frame.
[0018] Compared with the prior art, the beneficial effects of the present invention are:
[0019] When using this invention, if the vehicle is traveling on a bumpy road, the control lever vibrates. A push plate, in conjunction with a baffle, moves the push rod. The piston, under the influence of the thrust spring and the push rod, reciprocates, changing the air pressure inside the air tank. This, in turn, changes the air pressure inside the storage box. When air from the storage box is forced into the exhaust channel, ventilation is provided to the area where the user contacts the foam seat, preventing injury. When air from the exhaust channel is drawn into the storage box, a desiccant dries the air, ensuring the foam seat remains dry and improving user comfort.
[0020] When in use, this invention covers the foam seat in winter when the device is not in use. The L-shaped shield, combined with the first airbag, ensures a seamless fit between the top of the foam seat and the shield, improving protection and preventing rain and snow accumulation, thus avoiding any impact on the user's driving experience. When driving, the L-shaped shield is flipped over and stepped on by the user, causing it to contact the support strip. At this point, air from the second airbag is compressed into the first airbag, which then inflates and wraps around the user's legs, protecting them from cold winds and preventing injury from impacts.
[0021] In use, the invention uses a push-pull spring to provide damping for the sliding sleeve and a sliding groove to limit the slider, so that the operating handle is subjected to less vibration while adjusting the rotation angle of the control lever. This makes it easier for the user to grip the operating handle, improves the stability of its operation, and avoids traffic accidents. Attached Figure Description

[0030] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0031] Please see Figures 1-6 As shown, a stable three-wheeled electric scooter includes an electric scooter body 3 and a control lever 5 disposed on one side thereon. A support frame 2 is fixedly installed on the top of one end of the electric scooter body 3, and a shock-absorbing sleeve 6 for cushioning the control lever 5 is fixedly installed on the other end of the electric scooter body 3. The shock-absorbing sleeve 6 is prior art. An adjustment mechanism 8 for adjusting the rotation angle of the control lever 5 is movably disposed on the top of the control lever 5. A blower mechanism 7 for improving user comfort is disposed on the side wall of the shock-absorbing sleeve 6. A shielding mechanism 1 for preventing the support frame 2 from getting wet is movably disposed in the middle of the top surface of the electric scooter body 3.
[0032] Please see Figure 1 and Figure 2As shown, the blower mechanism 7 includes an air tank 706 fixedly connected to the shock-absorbing sleeve 6 via a connecting plate 703. A piston 704 is slidably disposed on the inner wall of the air tank 706. A push rod 707 is fixedly installed on the top of the piston 704. The top of the push rod 707 movably passes through the air tank 706 and is fixedly installed with a baffle 709. A first flexible hose 702 is fixedly inserted into the bottom of the air tank 706. One end of the first flexible hose 702 is provided with a seat unit 701 for supporting the user. When driving on bumpy roads, the control lever 5 is in a vibrating state. The push plate 708, in conjunction with the baffle 709, causes the air tank to vibrate. When the push rod 707 moves, the piston 704 reciprocates under the action of the thrust spring 705 and the push rod 707, thereby changing the air pressure in the air storage tank 706, which in turn changes the air pressure in the storage box 7011. When the air in the storage box 7011 is forced into the exhaust channel 7014, it ventilates the part of the user that is in contact with the sponge seat 7013, preventing injury to the body. When the air in the exhaust channel 7014 is drawn into the storage box 7011, it is dried by a desiccant, thereby ensuring that the sponge seat 7013 is dry and improving the user's comfort.
[0033] Please see Figure 1 and Figure 3 As shown, the aforementioned stool unit 701 includes a storage box 7011 connected to one end of the first flexible hose 702. The storage box 7011 contains a sufficient amount of desiccant, and the bottom of the storage box 7011 is elastically connected to the support frame 2 through several shock-absorbing springs. A sponge stool 7013 is attached to the top of the storage box 7011. Several longitudinally arranged exhaust channels 7014 are opened inside the sponge stool 7013. Several connecting pipes 7012 are fixedly inserted into the top of the storage box 7011. The connecting pipes 7012 are respectively inserted into the exhaust channels 7014, and the length of the connecting pipes 7012 extending into the exhaust channels 7014 is one-tenth of the depth of the exhaust channels 7014.
[0034] Please see Figure 2 As shown, a limiting sleeve is movably sleeved on the outer wall of the push rod 707 near the baffle 709, and a push plate 708 is fixedly installed on the limiting sleeve. A thrust spring 705 is elastically arranged between the top of the piston 704 and the inner wall of the gas storage tank 706.
[0035] Please see Figure 1 and Figure 4As shown, the aforementioned shielding mechanism 1 includes two rotating seats 103 fixedly connected to the electric scooter body 3. An L-shaped shield 101 is rotatably disposed between the two rotating seats 103. A first airbag 102 for covering the top surface of the sponge seat 7013 is fixedly disposed on the inner top wall of the L-shaped shield 101. A second hose 105 is connected to the first airbag 102, and one end of the second hose 105 passes through the L-shaped shield 101. When the device is not used in winter, the sponge seat 7013 is covered by the L-shaped shield 101, and at the same time, the first airbag 102 and the top of the sponge seat 7013 are fully covered. The seamless fit enhances the protection of the foam seat 7013, preventing rainwater and snow from accumulating on it and affecting the user's driving experience. When driving the device, the L-shaped shield 101 is flipped and stepped on by the user, causing it to contact the support bar 4. At this time, the air in the second airbag 104 is squeezed into the first airbag 102, and the inflated first airbag 102 wraps around the user's legs, preventing them from being affected by cold wind and avoiding injury from collisions.
[0036] Please see Figure 1 and Figure 4 As shown, a support bar 4 for limiting the rotation angle of the L-shaped shield 101 is fixedly installed on the electric scooter body 3. A second airbag 104 is fixedly installed on the electric scooter body 3 between the support bar 4 and the two rotating seats 103. The second airbag 104 is filled with sufficient air and is connected to one end of the second hose 105.
[0037] Please see Figure 1 and Figure 5 As shown, the aforementioned adjustment mechanism 8 includes a sliding sleeve 805 movably sleeved on the top of the control rod 5. Slide grooves 804 are provided on the inner walls of both sides of the sliding sleeve 805. Sliding sliders 802 are slidably disposed inside the slide grooves 804. Both sliders 802 are fixedly connected to the control rod 5. A push plate 708 is fixedly connected to the control rod 5, and a push-pull spring 803 is fixedly connected between the push plate 708 and the sliding sleeve 805. The push-pull spring 803 provides damping for the sliding sleeve 805, and the slide grooves 804 limit the movement of the sliders 802. This reduces vibration on the operating handle 9 while adjusting the rotation angle of the control rod 5, making it easier for the user to grip the operating handle 9, improving the stability of its operation, and preventing traffic accidents.
[0038] Please see Figure 1 As shown, an L-shaped frame 801 is fixedly installed on the outer wall of the aforementioned sliding sleeve 805, and an operating handle 9 is fixedly connected to the top of the L-shaped frame 801.
[0039] Please see Figure 1As shown, the bottom end of the control lever 5 is rotatably equipped with a first roller, and the bottom of the electric scooter body 3 near the support frame 2 is symmetrically equipped with two second rollers.
[0040] Working Principle: When using this invention, firstly, when the user drives the device on a bumpy road, the control lever 5 vibrates. The push plate 708, in conjunction with the baffle 709, moves the push rod 707. The piston 704, under the action of the thrust spring 705 and the push rod 707, reciprocates, thereby changing the air pressure in the air tank 706. This also changes the air pressure in the storage box 7011. When air from the storage box 7011 is forced into the exhaust channel 7014, ventilation is provided to the area where the user contacts the sponge seat 7013, preventing injury. When air from the exhaust channel 7014 is drawn into the storage box 7011, a desiccant dries the air, ensuring the sponge seat 7013 remains dry and improving user comfort. In winter, when the device is not in use, the L-shaped cover 101 covers the sponge seat 7013, simultaneously working with the first airbag 102 and the sponge seat... The top of the seat 7013 fits snugly without any blind spots, improving the protection efficiency of the foam seat 7013 and preventing rainwater and snow from accumulating on it, thus avoiding any impact on the user's driving experience. When driving the device, by flipping the L-shaped shield 101 and stepping on it with the user's feet, the L-shaped shield 101 comes into contact with the support bar 4. At this time, the air in the second airbag 104 is squeezed into the first airbag 102, and the inflated first airbag 102 wraps around the user's legs, not only preventing the user's legs from being affected by cold wind, but also preventing them from being injured by collisions. The push-pull spring 803 provides shock absorption to the sliding sleeve 805, and the sliding groove 804 limits the slider 802, so that the operating handle 9 can adjust the rotation angle of the control lever 5 while reducing the vibration, making it easier for the user to grasp the operating handle 9, improving the stability of its operation, and avoiding traffic accidents.
