Description

Technical Field

[0001] The invention belongs to the technical field of vehicle door stoppers and relates to a vehicle door stopper housing with a buffering function. Background Art

[0002] Door stoppers are usually installed on car doors. On the one hand, they are used to limit the opening angle of the door, including limiting the maximum opening of the door and stabilizing the door position at the designed opening and closing angle; on the other hand, they are used to provide door closing assistance to ensure user experience. Figure 1-3 As shown, a door stopper generally comprises a stopper arm 8, a stopper housing 1 that slides on the stopper arm 8, and sliders disposed within the stopper housing 1 and slidably clamped and fixed on both sides of the stopper arm 8. A buffer block 3 is also disposed on the stopper housing 1. Its working principle is as follows: one end of the stopper arm 8 is hinged to the vehicle body, the sliders are fixed to the vehicle door via the stopper housing 1, and a spring disposed between the slider and the stopper housing 1 presses the sliders against the stopper arm 1. When the vehicle door is opened, the stopper housing rotates with the vehicle door around the hinge end. Because the rotation axis of the door hinge end is not coaxial with the door axis, the stopper slider 2 moves outward along the stopper arm 8 as the door rotates until the buffer block 3 on the stopper housing 1 abuts the stopper block at the end of the stopper arm 8. At the same time, due to the high and low grooves formed on the stopper arm 8, the slider tends to stabilize at the lower end of the groove under the action of elastic force, thereby stabilizing the vehicle door at the designed opening angle.

[0003] like Figure 4 、 5 As shown, a buffer block mounting groove 2 is usually formed on the stopper housing 1, and a buffer block 3 is mounted on the stopper housing 1 by being embedded in the buffer block mounting groove 2 on one side. In actual use, after the buffer block 3 collides with the stopper multiple times, the connection between the buffer block 3 and the buffer block mounting groove 2 is often loose, and wear and tear or falling off occur, causing the stopper housing and the stopper block to directly collide, resulting in damage to the stopper housing or the stopper block. Summary of the Invention

[0004] The purpose of the present invention is to provide a vehicle door stopper housing with a buffering function.

[0005] The purpose of the present invention can be achieved by the following technical solutions:

[0006] A door stopper housing with a buffering function comprises a housing body, a buffer block mounting groove provided at one edge of the housing body and having an opening on one side wall, and a buffer block embedded in the buffer block mounting groove on one side, wherein the buffer block mounting groove is provided with an anti-pullout component.

[0007] The anti-slip assembly includes a U-shaped limit platform provided at the top of the three side walls of the buffer block installation groove and extending inward, transverse anti-slip protrusions provided on two opposite side walls of the U-shaped limit platform and extending relative to each other, and a longitudinal anti-slip beam mounted on the buffer block installation groove;

[0008] The buffer block is covered on the outside of the buffer block mounting groove, and the side wall is provided with a concave-convex matching structure that is compatible with the buffer block mounting groove, U-shaped limit platform, horizontal anti-pull-off protrusion, and longitudinal anti-pull-off beam, and is embedded in the buffer block mounting groove through the concave-convex matching structure.

[0009] Furthermore, the buffer block is integrally overmolded at the buffer block mounting groove.

[0010] Furthermore, the transverse anti-pullout protrusion is a rectangular parallelepiped protrusion.

[0011] Furthermore, a gap is provided between opposite side walls of the transverse anti-detachment protrusion.

[0012] Furthermore, a gap is provided between the transverse anti-slipping protrusion and the other side wall of the U-shaped limiting platform.

[0013] Furthermore, the transverse anti-slipping protrusion is arranged opposite to the longitudinal anti-slipping beam.

[0014] Furthermore, two buffer block mounting grooves are arranged side by side at one edge of the shell body, and an anti-pull-out component is provided on each buffer block mounting groove.

[0015] Furthermore, the longitudinal anti-pull-out beams in the two anti-pull-out components are integrally formed.

[0016] Furthermore, the side wall of the buffer block installation groove is arranged at an angle, so that the side wall is connected to the U-shaped limit platform at an acute angle.

[0017] Furthermore, a protrusion is provided at the inner corner of the buffer block installation groove.

[0018] Compared with the prior art, the present invention has the following characteristics:

[0019] 1) The present invention provides two transverse anti-detachment protrusions on two opposing side walls of the U-shaped limiter, and maintains gaps between the two transverse anti-detachment protrusions, between the transverse anti-detachment protrusion and the third side wall, and between the transverse anti-detachment protrusion and the bottom of the buffer block mounting groove. This allows the buffer block and the buffer block mounting groove to form a uniform and continuous mutual embedding structure during the buffer block overmolding process, thereby increasing the longitudinal and transverse pull-out forces of the two and ensuring a good bonding effect between the buffer and the limiter housing.

[0020] 2) The present invention further provides a longitudinal anti-pullout beam on the buffer block installation groove to further enrich the embedded structure, thereby enhancing the longitudinal and transverse pullout force between the buffer block and the buffer block installation groove.

[0035] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and specific operation process, but the protection scope of the present invention is not limited to the following embodiments.

[0036] Example:

[0037] like Figure 6 The door stopper housing with a buffering function shown in the figure comprises a housing body 1, two buffer block mounting grooves 2 arranged in parallel at one side edge of the housing body 1 and with an opening on one side wall, and a buffer block 3 integrally overmolded at the buffer block mounting groove 2.

[0038] like Figure 11-14 As shown, the buffer block mounting groove 2 is provided with an anti-pull-out component, which includes a protrusion 7 provided at the inner corner of the buffer block mounting groove 2, a U-shaped limit platform 4 provided at the top of the three side walls of the buffer block mounting groove 2 and extending inward, and horizontal anti-pull-out protrusions 5 respectively provided on the two opposite side walls of the U-shaped limit platform 4 and extending relative to each other, and a longitudinal anti-pull-out beam 6 integrally formed and mounted on the two buffer block mounting grooves 2.

[0039] like Figure 6-10 As shown, one side of the buffer block 3 is covered outside the buffer block mounting groove 2, and a concave-convex matching structure that matches the buffer block mounting groove 2, the U-shaped limit platform 4, the horizontal anti-pull-off protrusion 5, and the longitudinal anti-pull-off beam 6 is provided on the side wall, and is embedded in the buffer block mounting groove 2 through the concave-convex matching structure (as shown in FIG. Figure 15-16 shown).

[0040] Specifically, the lateral anti-pullout protrusion 5 is a rectangular protrusion, and a gap is provided between the opposite side walls of the lateral anti-pullout protrusion 5, and a gap is provided between the lateral anti-pullout protrusion 5 and the other side wall on the U-shaped limit platform 4. The above two gaps are connected to each other, so that the buffer block 3 can form a concave-convex matching substructure laterally embedded in the buffer block mounting groove 2 during the overmolding process, and the lateral anti-pullout protrusion 5 can be fully embedded in the substructure, thereby increasing the lateral pull-out force of the buffer block 3.

[0041] On the other hand, the transverse anti-pullout protrusion 5 fully embedded in the buffer block 3 also improves the longitudinal pullout force of the buffer block 3, thereby improving the bonding force between the housing body 1 and the buffer block 3.

[0042] At the same time, the longitudinal anti-pullout beam 6 mounted on the buffer block mounting groove 2 provides another buffer block embedding structure and further increases the pullout force of the buffer block 3 in the longitudinal direction.

[0043] In addition, in order to ensure the adhesion between the shell body 1 and the buffer block 3, the shell body 1, the buffer block installation groove 2 and the anti-pull-off component are integrally formed.

[0044] In other embodiments, the side wall of the buffer block mounting groove 2 is tilted so that the side wall is connected to the U-shaped limit platform 4 at an acute angle, and the transverse anti-pull-off protrusion 5 and the longitudinal anti-pull-off beam 6 are arranged opposite to each other to adapt to each other and enhance the anti-pull-off effect.

[0045] The above description of the embodiments is intended to facilitate understanding and use of the invention by those skilled in the art. It will be apparent that those skilled in the art can readily make various modifications to these embodiments and apply the general principles described herein to other embodiments without requiring inventive effort. Therefore, the present invention is not limited to the above-described embodiments. Improvements and modifications made by those skilled in the art based on the disclosure of the present invention, without departing from the scope of the present invention, should be within the scope of protection of the present invention.
