Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of protection of mobility scooters, in particular to an anti-collision buffer device for elderly mobility scooters. Background Art
[0002] Nowadays, in order to facilitate the travel of the elderly, they use mobility scooters. The anti-collision buffer technology of mobility scooters is a protective measure designed to improve safety when the elderly use mobility scooters. It aims to reduce or avoid injuries to the elderly in collision accidents, while also protecting the vehicle itself from serious damage.
[0003] The existing anti-collision buffer devices equipped on elderly scooters are usually equipped with a single set of buffers to provide buffering protection for the elderly scooters during use. The actual protection effect is not good. When the impact force of the elderly scooter is too large, it is still easy to cause damage to the body of the elderly scooter, and then cause injury to the driver in the elderly scooter. Utility Model Content
[0004] The present disclosure relates to an anti-collision buffer device for elderly scooters, which solves the problem that the anti-collision buffer device equipped on existing elderly scooters is usually equipped with a single set of buffers to provide buffering protection for the elderly scooters during use, and the actual protection effect is poor. When the impact force of the elderly scooter is too large, the body of the elderly scooter is still easily damaged.
[0005] In a first aspect of the present disclosure, an anti-collision buffer device for an electric scooter for the elderly is provided, which specifically includes: a base, a steel wire rope, a movable baffle, a middle frame, a connecting rod A, a connecting rod B and a tension spring; the base is fixedly connected to the electric scooter for the elderly, the outside of the base is connected to the steel wire rope, the outside of the base is connected to the connecting rod A, and the end of the connecting rod A is connected to the middle frame; the outside of the middle frame is connected to the connecting rod B, and the end of the connecting rod B is connected to the movable baffle, and the middle frame is located in the middle interval between the base and the movable baffle; the outside of the middle frame is connected to the tension spring.
[0006] Furthermore, the middle connecting frame is parallel to the base, one end of the connecting rod A is rotatably connected to the base, and the other end of the connecting rod A is rotatably connected to the middle connecting frame.
[0007] Furthermore, the movable baffle is parallel to the middle connecting frame, one end of the connecting rod B is rotatably connected to the movable baffle, and the other end of the connecting rod B is rotatably connected to the middle connecting frame.
[0008] Furthermore, a pulling hole is provided on the outside of the middle connecting frame, one end of the tension spring is connected to the pulling hole provided in one of the middle connecting frames, and the other end of the tension spring is connected to the pulling hole provided in the other middle connecting frame. When the movable baffle collides with an object, the movable baffle will move backward. Through the linkage action of the connecting rod A and the connecting rod B, the middle connecting frame moves outward, thereby increasing the distance between the two middle connecting frames. The tension spring is stretched and absorbs energy, effectively buffering the impact force exerted on the movable baffle.
[0009] Furthermore, a stopper is provided at the end of the steel wire rope, and a connecting hole is provided near the edge of the movable baffle, and the stopper is located in the connecting hole provided on the movable baffle.
[0010] Furthermore, a spring is sheathed on the outside of the steel wire rope, one end of the spring is in contact with the base, and the other end of the spring is in contact with the movable baffle. When the movable baffle moves backward, the spring is compressed by the thrust of the movable baffle, utilizing the elastic characteristics of the movable baffle to effectively assist in buffering the impact force borne by the movable baffle.
[0011] Furthermore, the left and right ends of the movable baffle are curved inward, and the outer side of the movable baffle is covered with a high-density sponge pad, which is centimeters thick. When the movable baffle accidentally collides with a passerby, the high-density sponge pad covering its surface can first contact the human body and exert an excellent cushioning effect.
[0012] The utility model provides an anti-collision buffer device for elderly scooters, which has the following beneficial effects:
[0013] When the utility model is in use, when the elderly scooter is driving, when the movable baffle collides with an object, the movable baffle will move backward, and through the linkage action of the connecting rod A and the connecting rod B, the middle connecting frame will move outward, thereby increasing the distance between the two middle connecting frames, and the tension spring is stretched and absorbs energy, effectively buffering the impact force exerted on the movable baffle, which can significantly reduce the damage to the elderly scooter caused by the collision. Through the effective buffering mechanism, the safety hazards caused by accidental collisions are reduced, the safety of users is protected, the structural damage caused by frequent collisions is alleviated, and the overall service life of the vehicle is extended.
[0014] In addition, when the movable baffle moves backward, the spring is compressed by the thrust of the movable baffle, and the elastic characteristics of the movable baffle are utilized to effectively assist in cushioning the impact force borne by the movable baffle, significantly improving the safety of the driver in the elderly scooter and greatly reducing the damage that may be caused to the elderly scooter itself by collision accidents; when the movable baffle accidentally collides with a passing pedestrian, the high-density sponge pad covering its surface can first contact the human body and exert an excellent cushioning effect, greatly reducing the impact force caused by direct collision, effectively dispersing pressure, and reducing the risk of injury to pedestrians.
