Description

Balance car wheel fixing mechanism and balance car

[Technical Field]

The present invention relates to the field of balancing vehicles, and more particularly to a balancing vehicle wheel securing mechanism and a balancing vehicle.

【Background technique】

Electric balance car, also known as body car, thinking car, its operation principle is mainly based on a basic principle called "dynamic stability", using the gyroscope and acceleration sensor inside the car body to detect the posture of the car body. Change and use the servo control system to accurately drive the motor to adjust accordingly to maintain the balance of the system.

There are two types of electric balance vehicles in the prior art. One type has an operating lever on the vehicle body, and the user stands on the pedal platform of the electric balance vehicle to operate the operating lever to advance, retreat and stop. Also known as "hand control." The other is that the car body is composed of two parts, and the left part and the right part are mutually rotated by the rotating mechanism, thereby realizing "foot control".

The existing balance car wheels occupy a larger place and require a larger space when not in use. And the wheels are easy to roll, and the balance car has no parking brakes, so it is easy to move.

[Summary of the Invention]

The technical problem to be solved by the present invention is to provide a balance car wheel fixing mechanism and a balance car that are convenient to be stored.

The object of the present invention is achieved by the following technical solutions:

According to an aspect of the present invention, a balance wheel fixing mechanism includes a vehicle body; a bottom of the vehicle body is provided with a groove, and the two sides of the groove are provided with a parallel a slide rail and a second slide rail; the second slide rail is located above the first slide rail, the first slide rail is provided with a connecting member; the wheel includes an axle component; and the axle component is provided with an embedded wheel The axle of the shaft is provided with a fixing member; the fixing member is movably connected with the connecting member; The stacked state can be embedded in the second slide of the groove.

According to another aspect of the present invention, the present invention also discloses a balance vehicle comprising the balance vehicle wheel securing mechanism of the present invention.

Compared with the prior art, the technical effect of the present invention is that the present invention uses a connecting member to connect the axle components, and the connecting member itself slides through the first sliding rail in the groove, so that the wheel can be translated when the wheel is folded, so that the whole wheel It can be completely stored in the bottom of the car body, further reducing the storage area of the balance car in the folded state of the wheel. In addition, the second slide rail in the groove can also keep the wheel stably folded. The presence of the groove itself can reduce the thickness of the vehicle in the folded state of the wheel. Furthermore, the axles are relatively thin, and it is not easy to realize a rotatable fixed structure. By the transfer of the fixing members, the contact area of the rotating shaft portion can be increased, and on the one hand, it is easy to be fixed with the connecting member, and on the other hand, the wheel is unfolded and the vehicle is deployed. Body side contact positioning improves stability when the wheel is running.

A balance wheel fixing mechanism and a balance car according to an embodiment of the present invention will be described below with reference to Figs.

The balance wheel fixing mechanism disclosed in the embodiment includes a vehicle body; the bottom of the vehicle body is provided with a groove, and the two sides of the groove are provided with parallel first sliding rails and second sliding rails; the second sliding rail a first upper rail is provided with a connecting member; the wheel includes an axle member; the axle member is provided with an axle embedded in the wheel; and the rotating shaft end is provided with a fixing member; The fixing member is movably connected to the connecting member; the fixing is fixed to the second sliding rail of the groove when the wheel is folded.

The connecting member includes a connecting plate and a first rotating shaft; the connecting plate is embedded in the first sliding rail; a connecting end of the connecting plate and the fixing member is provided with a notch; the first rotating shaft is disposed in the notch; The fixing member is embedded in the notch, and the fixing member is provided with a through hole that cooperates with the first rotating shaft. This is a specific rotatably connected structure. In addition, the connecting plate is integrally embedded in the first sliding rail, and the fixing strength is higher.

The connecting member further includes a second rotating shaft; the second rotating shaft is embedded in the first sliding rail; the first sliding rail end is further provided with an opening for exiting the second rotating shaft; the connecting plate can surround the second rotating shaft Rotating; the second rotating shaft is disposed at an end away from the fixing member. In this way, the connector itself can also be rotated, and the wheel has a more varied manner of movement. And because of the existence of the opening, when the wheel is turned over, the second shaft is pulled to the bottom, It is possible to withdraw from the first slide rail, and the entire connecting member and the wheel can be removed to facilitate the maintenance and repair of the balance vehicle.

One end of the connecting plate that cooperates with the second rotating shaft is provided with a bump, and the protruding block is provided with a through hole that cooperates with the second rotating shaft. This is a specific rotatably connected structure.

The opposite side of the fixing member from the axle is provided with a support portion movably coupled to the connecting member; the support portion is fixed at a position offset from the axle center of the axle. The support portion deviates from the axial center. When the balance vehicle is in operation, the support portion will naturally run to the lowest point due to the gravity and the human body pressure, forming a steady-state positioning structure. At this time, the fixing portion above the support portion has more area. The vehicle body is in contact with the side of the vehicle body, so that the wheel has a fixing member positioned in the vertical direction, and the bottom portion is supported by the connecting member at the bottom. The double-sided support can effectively disperse the bearing capacity of the wheel, and is more stable and durable.

Optionally, for the balance car controlled by the vehicle pole, the balance car further includes a vehicle bar that controls the steering of the balance car; the vehicle bar includes a fixed rod that is movably connected to the vehicle body, and a connecting rod that is rotatably connected with the fixed rod; The rod rotates the connected support rod; when in the fully folded state, the end of the support rod is in contact with the vehicle body. This structure allows the lever to lie down and realize the function of the leg control.

The connecting rod is flat. The connecting rod is placed horizontally and can be used as a stool.

The top of the support rod is a curved surface; the vehicle body is provided with a concave groove matching the curved surface; and the top side is provided with a foldable handle. This ensures that the axle can maintain effective support in the folded state, and can ensure flexible rotation of the axle and better leg control.

The fixed rod includes a first rod movably coupled to the vehicle body, and a second rod telescopically nested within the first rod; the connecting rod is rotatably coupled to the top end of the second rod. To achieve leg control, it is best to ensure that the height of the connecting rod exceeds the height of the human knee in the folded state, and the fixing rod can be telescopic, which can be used by people of different heights. Of course, the invention can also be applied to a balanceless car without a pole.

The above is a further detailed description of the present invention in connection with the specific preferred embodiments, and the specific embodiments of the present invention are not limited to the description. It will be apparent to those skilled in the art that the present invention may be made without departing from the spirit and scope of the invention.
