Description

Technical Field

[0001] This utility model relates to the field of electric vehicle protective frames, specifically to an adjustable protective frame and an electric vehicle. Background Technology

[0002] Electric vehicles are a type of transportation powered by rechargeable batteries. They are characterized by their flexibility, efficiency, and ease of use. Electric vehicles are widely used for personal transportation and passenger transport. However, safety is a primary concern for all electric vehicle manufacturers when traveling with children. Because children are naturally active and lack sufficient safety awareness, passengers typically place them on the footrest area in front of the vehicle to keep them within the driver's line of sight and provide better supervision. Electric vehicle safety frames generally provide effective protection for children through side and lower limb protection. However, children of different ages vary significantly in height and leg length. Existing electric vehicle safety frames often have fixed lower limb protection, making them difficult to adjust quickly and easily to suit the user's specific needs, thus limiting their practicality. Improving these aspects has become a pressing issue for those skilled in the art. Utility Model Content

[0003] To overcome the above shortcomings, this utility model provides an easily adjustable protective frame and electric vehicle, aiming to improve the problem that electric vehicle protective frames generally provide relatively effective safety protection for children through side and lower limb protection frames. However, children of different ages have significant differences in height and leg length, and the lower limb protection frames of existing electric vehicle protective frames are often fixed, making it impossible to make convenient and quick adjustments according to the user's specific situation and needs, resulting in relatively limited practicality.

[0004] This utility model is implemented as follows: In the first aspect, this utility model provides an easily adjustable protective frame, including a base, a side protection mechanism installed on one side of the base, a cavity provided in the base, an adjustment mechanism installed on the inner wall of the cavity, a lower limb protection mechanism installed at the upper end of the adjustment mechanism, and the lower limb protection mechanism being disposed above the base.

[0005] In a preferred embodiment of this utility model, the side protection mechanism includes a side plate, which is installed on one side of the base. A support plate is installed on the upper end of the side plate, and a reinforcing rod and a backrest are installed on one side of the support plate. One side of the backrest is connected to one end of the reinforcing rod. Protective frames are installed on both sides of the side plate, and a protective rod is connected to the inner end of the protective frame. The backrest is arranged in an arc shape. The two sets of protective frames, together with the protective rod, provide lateral protection for the child riding in the vehicle. A mounting seat is installed at the bottom of the base, and the base is installed on the electric vehicle through the mounting seat.

[0006] In a preferred embodiment of this utility model, the lower limb protection mechanism includes a lower limb protection frame, which is arc-shaped. The bottom two sides of the lower limb protection frame are connected to lower limb protection rods. A second reinforcing rod is connected to the inner end of the lower limb protection frame and one side of the lower limb protection rod. A connecting rod is installed at the bottom of the lower limb protection frame. A sliding groove is provided at the upper end of the base, and the sliding groove communicates with the cavity. The connecting rod is slidably connected within the sliding groove. The lower limb protection frame, lower limb protection rod, and second reinforcing rod work together to provide safety protection from the side of the child's lower limbs, preventing accidents during riding. The position of the lower limb protection mechanism can be adjusted using an adjustment mechanism in conjunction with the connecting rod, enhancing the device's adaptability to accommodate children of different ages and users with different leg lengths, thus increasing its flexibility.

[0007] In a preferred embodiment of this invention, the adjusting mechanism includes a lead screw rotatably mounted inside the cavity. A movable block is threaded onto the outside of the lead screw, and a connecting block is mounted on one side of the movable block. The top end of the connecting block is connected to the bottom end of the connecting rod, and a guide block is mounted on one side of the connecting block. A guide groove is provided on the inner wall of the cavity in cooperation with the guide block, and the guide block is slidably connected in the guide groove. Rotation of the lead screw causes the movable block to move, thereby moving the connecting rod. This allows the position of the lower limb protection mechanism to be conveniently and quickly adjusted according to the user's needs.

[0008] In the preferred embodiment of this utility model, a worm gear is fixedly sleeved on the outside of the lead screw, and a rod body is rotatably installed inside the cavity. A worm is installed at one end of the rod body, and the worm and the worm gear are meshed together. Rotation of the rod body causes the worm to rotate, which in turn drives the worm gear to rotate, causing the lead screw to rotate. At the same time, the self-locking property of the worm prevents the worm gear and the lead screw from rotating in opposite directions, thus avoiding affecting the stability of the lower limb protection mechanism. The operation is also more convenient and quick, saving a certain amount of operation time.

[0009] In a preferred embodiment of this utility model, the rod rotates through one side of the base, and an external support is installed at one end of the rod.

[0010] In a preferred embodiment of this utility model, the external support is configured as a rotating handle.

[0011] In a preferred embodiment of this utility model, a pad is provided at the upper end of the base, and the pad is elastically arranged.

[0012] Secondly, this utility model also provides an electric vehicle, including the aforementioned protective frame.

[0013] The beneficial effects of this utility model are as follows: This utility model provides an easily adjustable protective frame and electric vehicle through the above design. During use, two sets of protective frames, in conjunction with protective bars, provide lateral protection for the child riding the vehicle. The lower limb protective frame, lower limb protective bars, and a second reinforcing bar work together to provide safety protection from the side of the child's lower limbs, preventing accidents during riding. Depending on the user's situation, rotating the bar with an external support causes the worm gear to rotate, which in turn drives the worm wheel, causing the lead screw to rotate. This causes the moving block to move the connecting block, which in turn moves the connecting rod, allowing for convenient and quick adjustment of the lower limb protective mechanism's position according to the user's needs. This device, through the combination of lateral and lower limb protective mechanisms, effectively protects the user. The adjustment mechanism allows for convenient and quick adjustment of the lower limb protective mechanism's position according to the user's needs. Operation is simple, and it can accommodate children of different ages and users with different leg lengths, enhancing its flexibility. Attached Figure Description
