This application relates to the field of vehicle technology and discloses a sunshade device and a vehicle. The sunshade device provided by this application includes: a sunshade curtain, which includes a curtain body and a connecting component. One end of the curtain body is connected to the connecting component, and the connecting component is used to connect to the vehicle; a drive mechanism, which is used to drive the curtain body to move so that the curtain body switches between an unfolded state and a retracted state; and a locking mechanism, which includes a first limiting member and a second limiting member. The first limiting member is disposed at the end of the curtain body away from the connecting component, and the second limiting member is disposed on the connecting component. Thus, when the vehicle is parked outdoors, the curtain body can switch to an unfolded state and block the windshield to prevent sunlight from directly entering the vehicle through the windshield. When the vehicle is in motion, the curtain body can switch to a retracted state and be locked by the locking mechanism to prevent the curtain body from shaking.

This utility model relates to the field of welding helmet technology, specifically an adjustable head-mounted welding helmet, comprising a welding helmet body, with rotating rods rotatably connected to both sides of the welding helmet body. This utility model involves holding a rectangular block, which in turn moves a circular block via a vertical block. The circular block moves a circular rod, stretching a spring. The circular rod then moves a pointed block, separating it from an arc-shaped rubber strip. Rotating the rectangular block to the left causes the vertical rod to rotate the protective cover via the rotating rods. The protective cover then rotates the goggles upwards. When the goggles are rotated to the appropriate position, the tension on the rectangular block is released, and the spring force causes the circular block to move backwards. The circular block, through the circular rod, moves the pointed block into close contact with the arc-shaped rubber strip. This gives the head-mounted welding helmet an adjustable function, facilitating adjustment of the protective cover's rotation angle without obstructing vision. It also facilitates breathing, drinking, and other operations, improving work efficiency and providing convenience for the user.

This utility model belongs to the field of environmental detection technology, specifically relating to a drone for environmental detection. It includes a drone body with a camera assembly and a support mechanism located on its lower side. The support mechanism includes a rotating rod rotatably connected to the lower side of the drone body and driven by a micro-motor. A support component is also included, positioned below the drone body, with a support foot at its bottom. This support component can be rotated to a horizontal position via the rotating rod, extending beyond the flight wing. During flight in forests, it can prevent damage to the flight wing from collisions with branches and leaves, reducing the risk of drone crashes. This design does not obstruct the camera assembly's field of view, balancing protective functions with normal environmental detection operations, thus improving the drone's applicability in complex forest environments.

The utility model relates to a quick forging hydraulic press with a swing arm blank making function, which adopts a two-column structure and is simultaneously provided with a movable walking board, a centering mechanism and a transverse anvil moving mechanism, so that the quick forging function can be realized, and the centering and punching blank making can be completed, the centering mechanism is arranged on two supporting columns, and the transverse anvil moving mechanism is arranged on the supporting columns. Meanwhile, the included angle between the width direction of the movable walking board and the center connecting line of the two supporting columns ranges from 35 degrees to 40 degrees, the transverse anvil moving mechanism and the movable walking board are arranged in a 90-degree crossed mode, in this way, the view field is not affected, and the supporting columns can be centered in the direction of the center connecting line of the two supporting columns; and interference among the movable walking board, the centering mechanism and the transverse anvil moving mechanism is avoided, and the working efficiency is improved.
