Description

Technical Field

[0001] The present application relates to the field of mobility scooters, and in particular to a folding seat structure of a mobility scooter and a folding mobility scooter. Background Art

[0002] At present, with the significant increase in society's attention to barrier-free travel environments, a wide variety of mobility scooters have emerged on the market for patients, the elderly, the disabled and other groups with limited mobility, greatly promoting the improvement of these groups' quality of life and the enhancement of their travel autonomy. However, although these mobility scooters are designed to fully cover diverse travel needs, their relatively large size has encountered multiple challenges in actual application.

[0003] The primary problem is the lack of portability. Many mobility scooters are complex in structure and heavy in weight, making it difficult for users to carry them to public transportation facilities or to transfer them manually over short distances. This is particularly true when users need to flexibly switch between travel modes or face natural obstacles such as stairs and steps, which greatly limits their convenience of use.

[0004] Secondly, the storage problem needs to be solved urgently. For families with compact living space, the placement of large mobility scooters has become a big problem. Similarly, in public places that provide mobility services such as hospitals and shopping malls, there is also the challenge of how to efficiently and reasonably plan storage space to ensure that the equipment is always available and well maintained.

[0005] In addition, the inconvenience of transportation further limits the scope of application of mobility scooters. When it comes to cross-regional or long-distance movement, the size and weight of mobility scooters often become a heavy burden during transportation. Whether it is carried by private cars or relies on logistics transportation, it adds additional economic costs and operational complexity, thus affecting its wider application and popularity. Utility Model Content

[0006] The purpose of the embodiments of the present application is to provide a folding seat structure of a mobility scooter and a folding mobility scooter, so as to solve the problems of existing mobility scooters that are inconvenient to carry, store and transport.

[0007] An embodiment of the present application provides a folding seat structure of a mobility scooter, the folding seat structure being arranged on a vehicle frame, the folding seat structure comprising: a front arm, a rear arm and a seat bracket;

[0008] The bottom end of the front arm is hinged to the frame, and the bottom end of the rear arm is hinged to the frame;

[0009] The top end of the front arm is hinged to the front end of the seat bracket, and the top end of the rear arm is hinged to the rear end of the seat bracket;

[0010] The top end of the forearm is provided with a groove; the front end of the seat bracket is provided with a sliding groove and a sliding component, and the sliding component slides in the sliding groove;

[0011] When the sliding assembly is slid into the groove of the front arm, the seat bracket, the front arm and the rear arm are fixed.

[0012] In the above technical solution, the top of the forearm has a groove, and the sliding groove is set at the front end of the seat bracket. When the folding seat needs to be unfolded, the seat bracket is raised until the sliding groove is opposite to the groove of the forearm. At this time, the sliding component is slid into the groove of the forearm to fix the seat bracket, forearm and rear arm. Afterwards, when the folding seat needs to be folded, the sliding component is moved away from the groove of the forearm to unlock it, and then the seat bracket is lowered. Through the design of the folding seat structure, the size of the scooter can be greatly reduced when not in use, making it easy for users to carry it to public transportation, carry it manually over short distances, or store it in a limited space, thereby improving portability, optimizing storage space, and enhancing transportation convenience.

[0013] In some optional embodiments, the frame includes a front axle and a rear axle, the bottom end of the front arm is hinged to the front axle, and the bottom end of the rear arm is hinged to the rear axle.

[0014] In some optional embodiments, the folding seat structure includes two front arms, and the two front arms are respectively arranged on both sides of the rear arm.

[0015] In the above technical solution, the range of motion of the two front arms and the rear arms does not interfere with each other, and the folding seat can be folded and unfolded more smoothly, avoiding jamming or damage caused by mutual obstruction between components. In addition, the two front arms and the rear arms are in the same plane with the bottom of the frame in the folded state, which can greatly reduce the volume.

[0016] In some optional embodiments, longitudinal beams are respectively provided on both sides of the seat support.

[0017] In the above technical solution, the setting of the longitudinal beam significantly enhances the overall structural stability of the seat frame and provides a more solid support foundation for the seat. This design allows the seat to disperse stress when bearing weight, avoiding excessive stress at a single point, thereby extending the service life of the seat. By adding the longitudinal beam, the load-bearing capacity of the seat frame is significantly improved. This means that the seat can bear heavier loads more safely and meet the needs of different users.

[0023] In the above technical solution, a spring is arranged near the sliding groove to pull or push the sliding rod to move toward the forearm. After the user adjusts the seat bracket to a suitable height, the groove of the forearm faces the sliding groove. Through the pulling or pushing action of the spring, the sliding rod automatically enters the groove to fix the seat bracket. If the height of the seat bracket needs to be further adjusted, the user only needs to pull the sliding rod away from the groove to unlock it, which improves the convenience of adjustment, simplifies the adjustment process, and improves the user experience.

[0024] In some optional embodiments, a first crossbar is provided at the front end of the seat support, and a second crossbar is provided at the rear end of the seat support; both ends of the first crossbar are fixed to the front ends of the two longitudinal beams, and both ends of the second crossbar are fixed to the rear ends of the two longitudinal beams;

[0025] The top end of the front arm is hinged to the first crossbar, and the top end of the rear arm is hinged to the second crossbar.

[0026] In some optional embodiments, a first groove is provided at the top of the forearm;

[0027] When the sliding assembly slides into the first groove, the folding seat structure is in a fully unfolded state.
