This application relates to a bracket assembly, a windshield assembly, and a vehicle. When an optical element is assembled on the bracket body or removed, the limiting member is in a loosened position, and each abutment part and clamping arm is separated from each other. When the fixed shaft is inserted between the two clamping arms, it can push the two clamping arms apart. When the fixed shaft is pulled out of the two clamping arms, it can also push the two clamping arms apart. When the optical element is inserted between the two clamping arms, the limiting member is in a pressed position, and each abutment part abuts against each clamping arm, so that the two clamping arms are tightly abutted against the opposite sides of the fixed shaft. This ensures that the insertion force of the optical element is small and the extraction force is large during the assembly process. In addition, the tension of the retaining spring remains unchanged, and the extraction force between the retaining spring and the fixed shaft is stable over a long period of time. Furthermore, the interference fit between the retaining spring and the fixed shaft can be reduced to reduce the insertion force.

The present application relates to the field of towing seat, specifically to the magnetic force self-locking towing seat, including towing seat shell, the inside articulated pawl of towing seat shell, the inside linear slide rail of towing seat shell is set up, the inside of linear slide rail is provided with the guide drive mechanism for starting when entering by towing pin, the present application is switched by ingenious magnetic circuit design, makes the tow pin in the process of insertion mechanical drive magnet two rotation, automatically changes its with fixed magnet one magnetic pole opposite relation, thereby in the absence of external power, intelligent control magnetic field generation and blanking.When the magnetic pole is in the same direction, the magnetic field is guided out through the metal sheet, forming strong suction force, the pawl is quickly attracted, realizing the instantaneous locking of magnetic force auxiliary.The process greatly reduces the insertion force and impact noise required by pure mechanical locking, makes the connection action more smooth, soft, and the magnetic attraction force ensures the sufficiency and consistency of locking, improves the connection reliability and operation experience.

The application discloses a piece contact plug-in structure, which comprises a spring piece and a clamping shell, the spring piece is arranged in the clamping shell, the spring piece comprises an upper spring piece and a lower spring piece which are arranged in an up-down mode and form a plug-in slot, the upper spring piece and the lower spring piece each comprise a spring piece base body, the spring piece base body is provided with a first cantilever and a second cantilever, the second cantilever is located in a different height plane from the first cantilever, the gap between the first cantilever and the second cantilever is infinitely reduced to zero, the number of cantilevers is increased, the number of contact points is increased, the conductive performance is improved, the conductive performance is improved, the width of the spring piece base body is fully utilized, the spring piece body resistance is reduced, the current carrying capacity of the spring piece is improved, and the problem that in the prior art piece contact, the number of cantilevers and the spring piece body resistance value are fixed without increasing the width of the spring piece base body, the conductive performance and the current carrying capacity are fixed, and the conductive performance and the current carrying capacity cannot be improved is solved.

The utility model discloses a male and female riveting terminal, and relates to the field of electric connectors. Comprising a male terminal and a female terminal, a connecting plug is formed at the front end of the male terminal, a male end wire riveting part is formed at the rear end of the male terminal, a connecting port is formed at the front end of the female terminal, a female end wire riveting part is formed at the rear end of the female terminal, at least one male end gap is formed in the side portion of the connecting plug, and the male end gap extends from the rear end of the connecting plug to the end portion of the front end. And the end part extends towards the left side and the right side to form an arc-shaped opening. The front end portion of the crack expands towards the left side and the right side to form arc-shaped openings, the structural design enables the connecting plug to have elastic deformation capacity in the inserting process so as to adapt to dimensional tolerance or assembly deviation of the connecting plug, and meanwhile the left arc-shaped opening and the right arc-shaped opening in the tail end of the crack provide flexible buffering and self-alignment guiding functions in the inserting and pulling process. Therefore, the insertion force is effectively reduced, and the insertion smoothness and stability are improved.
