In the specific embodiments provided by the present disclosure, the ball mount may be configured in any suitable manner. Referring to fig. 1 to 3, the ball snap seat may include a main body 11 and a plurality of elastic locking tongues 12, the main body 11 is provided with a ball fitting hole 13, the elastic locking tongues 1212 are disposed in the ball fitting hole 13 and connected to the main body 11, and the plurality of elastic locking tongues 12 are disposed at intervals around a central axis of the ball fitting hole 13.

When the automobile door is assembled, the elastic clamping tongue 12 is elastically deformed under the extrusion of the ball head 51, so that the ball head 51 on the inner door panel 5 enters the ball head matching hole 13, and when the ball head 51 passes over the elastic clamping tongue 12, the elastic clamping tongue 12 is restored to be deformed so as to stop the retraction movement of the ball head 51, thereby realizing the matching connection of the ball head 51 and the ball head clamping seat.

Along the central axis of the ball head fitting hole 13, the main body 11 may include a first end 111 and a second end 112 opposite to each other, and define a first direction from the first end 111 to the second end 112, and a second direction from the second end 112 to the first end 111, the elastic latch 12 includes a proximal end 121 and a distal end 122 opposite to each other, the proximal end 121 is connected to the first end 111, the second end 112 is connected to the collapsing part 3, as shown in fig. 1, 2 and 5, the elastic latch 12 extends obliquely inward from the proximal end 121 to the distal end 122 in the first direction, an oblique angle between the distal end 122 and an end surface of the first end 111 may be any suitable value, and a distance between two adjacent elastic latches 12 may gradually increase from the proximal end 121 to the distal end 122 to allow a space to be reserved between two adjacent elastic latches 12 when the elastic latches 12 deform. The elastic latch 12 allows the ball 51 to move in a first direction and stops the ball 51 from moving in a second direction through the distal end 122, and the ball fitting hole 13 may be configured as follows: in the event of a crash, the ball 51 secured to the door inner panel 5 may be allowed to continue to move in the first direction beyond the distal end 122, dumping a portion of the crash energy, and providing a cushioning effect, which may also be understood herein as being absorbed.

Referring to fig. 1 and 3, the guide limit structure 4 is formed with a guide limit surface 41 for limiting a moving track of the ball head 51. The guide limiting surface 41 may have a circular arc cross section, the radius of curvature of the circular arc is equal to the radius of curvature of the ball 51, and the center of the circular arc is located on the central axis of the ball fitting hole 13.

In the specific embodiment provided by the present disclosure, the guiding and limiting structure 4 is disposed between every two adjacent elastic latch tongues 12, so that the elastic latch tongues 12 and the guiding and limiting structure 4 are disposed in a staggered manner around the central axis of the ball fitting hole 13, and while the distal ends 122 of the elastic latch tongues 12 stop the movement of the ball 51 along the second direction, the guiding and limiting structure 4 limits the movement of the ball 51 in the radial direction perpendicular to the central axis, so as to achieve a good fixing effect between the door inner panel 5 and the door trim panel 6.

In the specific embodiment provided by the present disclosure, the elastic latch 12 and the guiding and limiting structure 4 may be configured with a ball and socket structure at a side corresponding to the first end 111 to guide the insertion of the ball 51 into the ball socket while allowing the insertion of the ball 51 into the ball socket at any suitable angle to facilitate the mating connection between the ball 51 and the ball socket.

In addition, in the embodiment provided by the present disclosure, the ball snap includes a mounting portion 2 detachably mounted on the door trim 6 and a crush portion 3 connecting the body 11 and the mounting portion 2 to each other, the crush portion 3 is configured to be crushed by an impact of a predetermined force, wherein the crush portion 3 includes a solid portion 31 and a hollow portion 32, and the solid portion 31 is connected between an outer side of the second end 112 and the mounting portion 2. In other embodiments provided by the present disclosure, the ball snap seat may be integrally formed with the door trim 6, and the present disclosure is not particularly limited thereto.

When a vehicle is impacted, impact force from the inner plate 5 of the vehicle door acts on the crumpling part 3 through the ball head buckle seat, and the crumpling part 3 is cracked under the impact force to realize crumpling and energy absorption so as to reduce the damage of vehicle parts to a human body in collision. Through the crumple energy absorption of the crumple part 3, the collision energy acting on a passenger can be reduced, so that the secondary damage of a vehicle door to a human body when the vehicle is collided laterally is reduced or even avoided, and the safety performance of the vehicle is improved.

In the specific embodiments provided by the present disclosure, the crush section 3 can be configured in any suitable manner. Referring to fig. 1, 2 and 4, the crush portion 3 may include a solid portion 31 and a hollowed-out portion 32, the solid portion 31 being connected between the outside of the body 11 and the mounting portion 2, the hollowed-out portion 32 enabling the solid portion 31 to be more easily broken when being impacted by a collision. The solid portions 31 and the hollow portions 32 may be configured in plural, the plural solid portions 31 are arranged at intervals along the periphery of the main body 11, and the hollow portion 32 is between two adjacent solid portions 31.

In the specific embodiments provided by the present disclosure, solid portion 31 may be configured in any suitable manner. The solid portion 31 may be configured as a fan-shaped structure gradually widening from the inside to the outside in a radial direction perpendicular to the central axis of the ball joint hole 13. The "inner and outer" are positions with respect to the center axis of the ball fitting hole 13, and the direction toward the center axis is "inner" and vice versa. As can be seen from the fan-shaped structure of the solid portion 31 shown in fig. 1, 2, and 4, the widest portion of the fan-shaped structure is connected to the mounting portion 2 so that the connection between the door inner panel 5 and the door trim panel 6 is stabilized; the narrowest part of the fan-shaped structure is connected to the outside of the body 11, where it is more likely to collapse upon impact.

In the specific embodiments provided in the present disclosure, it is required to ensure that the collapsed portion 3 does not collapse when the collapsed portion 3 is subjected to an external force less than a preset acting force. Thus, in order to enhance the connection stability between the door inner panel 5 and the door trim 6, a side surface (e.g., a side surface facing the latch portion 1, or the other opposite side surface) of the crush portion 3 may be provided with a reinforcement rib 33, so that the crush portion 3 is crushed when an external force equal to or greater than a predetermined force is applied. The reinforcing rib 33 may be disposed along the edge of the crush portion 3, or may be configured as a rib having a cross shape or a triangular shape, and the disclosure is not limited thereto. In the embodiment shown in fig. 3, the guide stopper surface 41 extends to the solid portion 31 and the reinforcing rib 33 to increase the range of the guide.

In the embodiments provided in the present disclosure, the mounting portion 2 may be configured in any suitable manner, for example, the mounting portion 2 may be configured with a plug structure for plug connection with the door trim 6, and during assembly, referring to fig. 6 and 7, the mounting portion 2 is first fixed to the door trim 6 and then is in fit connection with the ball 51 on the door inner panel 5, thereby completing the assembly of the door inner panel 5 and the door trim 6, and during disassembly, the mounting portion 2 is removed in the opposite direction. Therefore, the quick assembly and disassembly can be realized, and the production efficiency is improved.
