Description

Technical Field

[0001] This utility model relates to the field of cycling suitcase technology, and more specifically, to an auxiliary steering handle for cycling suitcases. Background Technology

[0002] Against the backdrop of increasingly diverse modern travel needs, the cycling suitcase has emerged as a travel gear that combines cycling and towing functions. Traditional suitcases can only be pulled by manpower, and users often feel exhausted when traveling long distances or carrying heavy objects.

[0003] In terms of steering, without an efficient power assist mechanism, the steering of ordinary rolling suitcases relies directly on the rider's hand strength to drive the front wheel. When loaded with a large amount of luggage, the weight of the suitcase increases, and the steering resistance increases significantly. The rider needs to exert a lot of effort to turn the handlebars, which can easily cause hand fatigue and soreness, and may even make it impossible to control the steering in a timely and accurate manner in an emergency, causing safety hazards. Utility Model Content

[0004] In order to overcome the problems and defects in the prior art, this utility model provides an auxiliary steering handle for a riding suitcase to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an auxiliary steering handle for a riding suitcase, including a steering handle installed on the top of the riding suitcase, a movable wheel installed at the bottom of the riding suitcase, a drive wheel installed on the bottom of the riding suitcase away from the movable wheel, and an auxiliary steering mechanism provided between the riding suitcase and the steering handle;

[0006] The auxiliary steering mechanism includes a fixed sleeve, which is fixed to one side of the inner wall of the riding suitcase. A fixed column is rotatably connected inside the fixed sleeve. A square groove is formed on the top surface of the fixed column. A motor is fixedly installed at the bottom of the inner wall of the square groove. A threaded rod is fixedly connected to the output end of the motor. A lifting column is provided at the top of the threaded rod. A threaded groove is formed on the bottom surface of the lifting column. A sleeve is fixedly connected to the top of the lifting column. The sleeve is fixedly connected to the steering handle. A multi-stage transmission mechanism is provided at the bottom of the fixed column.

[0007] Preferably, the multi-stage transmission mechanism includes a fixed shaft, which is fixed to the bottom of a fixed column, and a first gear is mounted on the bottom of the fixed shaft.

[0008] Preferably, a second gear meshes with one side of the first gear, a rotating shaft is fixedly connected inside the second gear, a fixed plate is rotatably connected to the top of the rotating shaft, and the bottom of the fixed plate is fixedly connected to the inner wall of the riding suitcase.

[0009] Preferably, a first torque gear is fixedly sleeved on the outer side of the rotating shaft, and a second torque gear meshes with one side of the first torque gear.

[0010] Preferably, a front fork is fixedly connected inside the second torque gear, and the front fork is installed between the drive wheel and the riding suitcase.

[0011] Preferably, a connecting sleeve is fixedly installed on the top of the riding suitcase, and the connecting sleeve is slidably connected to the lifting column.

[0012] Preferably, the outer side of the steering handle is fitted with an anti-slip sleeve.

[0013] Preferably, the lifting column is slidably connected to the square groove, and the threaded rod is threadedly connected to the threaded groove.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] By incorporating an auxiliary steering mechanism, the motor-driven lifting column automatically adjusts the height of the steering handlebars, allowing riders to quickly raise the handlebars to a comfortable grip position without having to bend over or lift their hands. This facilitates easy steering operation and greatly enhances usability. The ingeniously designed multi-stage transmission mechanism transmits power layer by layer through the first gear, second gear, first torque gear, and second torque gear. The multiple gear transmissions amplify the torque, effectively increasing the steering force. This means that even when riding a suitcase carrying heavy items, riders only need to exert minimal effort to easily steer the drive wheel, significantly reducing steering difficulty and physical exertion, making the riding process easier and smoother.

[0016] By equipping the outside of the steering handle with an anti-slip sleeve, the friction between the hand and the handle is increased, effectively preventing slippage caused by factors such as sweaty hands, shaking, or external impacts during riding and turning. This ensures that the rider can control the steering stably and accurately, guaranteeing riding safety. When the auxiliary steering function is not needed, the motor reverses to drive the lifting column to descend, and the steering handle is lowered and stored accordingly, so that it does not take up extra space and will not obstruct the normal dragging of the riding suitcase.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] As attached Figure 1-6 The auxiliary steering handle of the riding suitcase shown includes a steering handle 12 installed on the top of the riding suitcase 1, a movable wheel 2 installed at the bottom of the riding suitcase 1, a drive wheel 3 installed on the bottom of the riding suitcase 1 away from the movable wheel 2, and an auxiliary steering mechanism provided between the riding suitcase 1 and the steering handle 12.

[0026] The auxiliary steering mechanism includes a fixed sleeve 4, which is fixed to one side of the inner wall of the riding trolley case 1. A fixed column 5 is rotatably connected inside the fixed sleeve 4. A square groove 6 is opened on the top surface of the fixed column 5. A motor 7 is fixedly installed at the bottom of the inner wall of the square groove 6. A threaded rod 8 is fixedly connected to the output end of the motor 7. A lifting column 9 is set on the top of the threaded rod 8. A threaded groove 10 is opened on the bottom surface of the lifting column 9. A sleeve 11 is fixedly connected to the top of the lifting column 9. The sleeve 11 is fixedly connected to the steering handle 12. A multi-stage transmission mechanism is set at the bottom of the fixed column 5.

[0027] As attached Figure 3 , 4As shown in Figure 6, the multi-stage transmission mechanism includes a fixed shaft 14, which is fixed to the bottom of the fixed column 5. A first gear 15 is installed at the bottom of the fixed shaft 14. A second gear 16 meshes with one side of the first gear 15. A rotating shaft 17 is fixedly connected inside the second gear 16. A fixed plate 18 is rotatably connected to the top of the rotating shaft 17. The bottom of the fixed plate 18 is fixedly connected to the inner wall of the riding trolley case 1. A first torque gear 19 is fixedly sleeved on the outside of the rotating shaft 17. A second torque gear 20 meshes with one side of the first torque gear 19. This facilitates increasing torque through multi-stage transmission, and can easily achieve steering operation even under heavy load.

[0028] As attached Figure 3 , 6 As shown, a front fork 21 is fixedly connected inside the second torque gear 20. The front fork 21 is installed between the drive wheel 3 and the riding trolley case 1, so that the drive wheel 3 can be rotated after transmission to complete the steering.

[0029] As attached Figure 1-3 As shown, a connecting sleeve 22 is fixedly installed on the top of the riding suitcase 1. The connecting sleeve 22 is slidably connected to the lifting column 9, which facilitates the connection and limit function and ensures the lifting stability of the lifting column 9.

[0030] As attached Figure 1 , 3 As shown, an anti-slip sleeve 13 is fixedly fitted on the outer side of the steering handle 12 to prevent insufficient friction of the steering handle 12 from affecting steering accuracy.

[0031] As attached Figure 3-5 As shown, the lifting column 9 is slidably connected to the square groove 6, and the threaded rod 8 is threadedly connected to the threaded groove 10, which facilitates the lifting of the lifting column 9, thereby facilitating the lifting of the steering handle 12, making it suitable for people of different heights.

[0032] The working principle of this utility model is as follows: When the auxiliary steering function of the riding suitcase is needed, the motor 7 is first started. Since the output end of the motor 7 is fixedly connected to the threaded rod 8, and the threaded rod 8 is threadedly connected to the threaded groove 10 at the bottom of the lifting column 9, while the lifting column 9 is slidably connected to the square groove 6, when the motor 7 drives the threaded rod 8 to rotate, the lifting column 9 will move upward along the square groove 6. As the lifting column 9 rises, the sleeve 11 fixedly connected to its top will drive the steering handle 12 to rise together until a suitable operating height is reached, making it convenient for the rider to hold the steering handle 12. The anti-slip sleeve 13 on the outside of the steering handle 12 can effectively increase the friction between the hand and the handle and prevent slippage.

[0033] When the rider turns the steering handlebar 12, the force is transmitted to the rising column 9 through the sleeve 11, and then to the fixed column 5 through the rising column 9. The fixed column 5 rotates within the fixed sleeve 4, and the fixed shaft 14 at the bottom of the fixed column 5 rotates accordingly. The first gear 15 installed at the bottom of the fixed shaft 14 also rotates synchronously. Since the first gear 15 meshes with the second gear 16, the rotation of the first gear 15 drives the second gear 16 to rotate around the rotating shaft 17. The top of the rotating shaft 17 is rotatably connected to the fixed plate 18, which is fixed to the inner wall of the riding trolley case 1, providing stable support for the rotating shaft 17. As the second gear 16 rotates, the first torque gear 19 fixedly sleeved on its outer side also rotates. The first torque gear 19 meshes with the second torque gear 20, thereby driving the second... The torque gear 20 rotates, and the front fork 21 is fixedly connected inside the second torque gear 20. The front fork 21 is installed between the drive wheel 3 and the riding suitcase 1. The rotation of the front fork 21 ultimately drives the drive wheel 3 to turn. Through such a multi-stage transmission mechanism, each stage of gear transmission plays a role in increasing torque, which increases the torque transmitted to the drive wheel 3. Even if the riding suitcase is heavily loaded, the rider can easily achieve steering operation, greatly reducing the steering effort. When the auxiliary steering function is not used, the motor 7 reverses, driving the lifting column 9 to descend, and the steering handle 12 is lowered and stored accordingly, without affecting the normal dragging use of the riding suitcase. The sliding connection between the connecting sleeve 22 at the top of the riding suitcase 1 and the lifting column 9 ensures the smoothness of the lifting column 9 during the lifting process.

[0034] In conclusion, the above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
